Relooper algorithms are used for decompiling code. While an important topic, it doesn't seem particularly relevant to programming language design. – curiousdannii Nov 19 '22 at 9:02

@curiousdannii Relooper is relevant to compiling to wasm if the source language has gotos or other forms of control flow not supported by wasm. – Bubbler Nov 20 '22 at 1:38

@curiousdannii area51.meta.stackexchange.com/questions/32843/… – mousetail Nov 22 '22 at 6:51

Even if that is the case, I'd prefer a question that asks it from the perspective of implementation. E.g. "How should I compile my goto into wasm?" – Nathan Merrill Dec 1 '22 at 19:57

Hmm yeah, makes sense. I'll change it. – Bubbler Dec 1 '22 at 23:20

A question like "why not" should probably be phrased more like "what are the downsides of", particularly in this case where many languages do make all strings immutable. – kaya3 Dec 1 '22 at 13:26

	By "handling big numbers", do you mean "having a built-in arbitrary-precision integer type"? Do you mean "having such a type exclusively, without also supporting concretely sized integer types"? Or just what? – Anonymous Jan 12 '23 at 19:39
	@Anoymous I mean "having a built-in arbitrary-precision integer type", specifically more than 64 bits. – justANewbie Jan 13 '23 at 7:40

might be better as a looser questions, like the tradeoffs between types of strings and numbers? – cjquines Feb 5 '23 at 10:17

	what do you mean by "eval"? – warren Jan 25 '23 at 17:33
	Like the eval function in JS or python – mousetail Jan 25 '23 at 17:43

This seems a little too open-ended. Perhaps this could be split into questions about generating bytecode, reading bytecode, Java interop, etc.? – Original Original Original VI Nov 18 '22 at 16:59

Yeah now I agree. Will edit. – Seggan Nov 18 '22 at 17:01

Are they? Java's implementation of them might be unwieldy, but I've never heard criticism of the concept itself. – Unrelated String Nov 28 '22 at 4:02

As far as I tell, the primary complaint that I see is that it's not uncommon to get in situations where a method is declaring multiple distinct checked exceptions, and that the frequency of handling them causes developers to frequently suppress them. Even then, I think an answer that says "Checked exceptions are poorly regarded because of Java, here's a better way to do them", would be a fine answer to this question. – Nathan Merrill Dec 1 '22 at 20:09

Perhaps it could be asked about Java in particular? – user3840170 Dec 19 '22 at 11:13

This isn't a question. – Ray Butterworth Jan 12 '23 at 20:16

It's phrased poorly, but it is a legitimate, if subjective, question about programming language design. Granted, I don't think we'd need a whole question about the "billion dollar mistake" either--it's a bit too straightforward... – Unrelated String Jan 15 '23 at 9:52

This seems much too vague and unfocused to be answerable. Which optimizations would you be considering? – Anonymous Jan 12 '23 at 19:58

English grammar demands noun phrases here; adjectival phrases don't nominalize implicitly. So: "... strong typing vs weak typing?" Alternately: "strongly typed vs weakly typed languages?", allowing the adjectival phrases to modify something. – Anonymous Jan 12 '23 at 19:34

I can't say this is clearly out of scope, but I wouldn't call it a good question. Line numbers are transparently an artifact of punch cards, unstructured programming, and primitive editors; it's hard to imagine why they would stick around. – Unrelated String Jan 26 '23 at 3:48

@UnrelatedString - if this proposal is about implementation, too (per the name and description), implementing a classic language could be of interest :) – warren Jan 27 '23 at 14:08

Is this about parsing a source change into an AST change? That’s typically called “incremental parsing”. “Iterative parsing” as a term of art seems to either contrast with “recursive parsing”, or refer to parsing in multiple, increasingly specific passes. – Jon Purdy Nov 18 '22 at 17:44

I think fundamentally, this is a good question, but I'd prefer "storing" over "dealing with", as "dealing" is a bit vague. – Nathan Merrill Dec 1 '22 at 19:59

@NathanMerrill I intended to include things like slicing, indexing, counting, etc. – Adám Dec 1 '22 at 22:00

"How can unicode text data be indexed?" would be a more specific question. Slicing is just indexing twice, and counting is somewhat implied since the number of characters is equal to the last index plus one (though "how can I count characters in Unicode text data?" might work as a separate question). – kaya3 Dec 2 '22 at 13:39

@Adám - made a tweak so it's more inline with what you're proposing – warren Dec 5 '22 at 16:54

I think there would rather be a question about what gotchas exist in dealing with Unicode (which could be answered by highlighting topics like collation, characters composed of multiple code points etc.), and then separate questions about how to deal with each of those. – Anonymous Jan 12 '23 at 19:38
