@Leaf Are there any strong arguments against adopting UTS #31 ("Identifier and Pattern Syntax") in the next version of C (C23)? Talking with someone who is apparently discussing the proposal tomorrow, and I recall you had Opinions about emoji in identifiers (which that would seem to preclude).
the main argument against is that it means the set of characters allowed in identifiers is constantly expanding. the reason why languages like swift or XML don't take that approach is because they want the lexical grammar to be relatively fixed. (support for emoji is usually an accident of that which springs from allowing anything greater than U+FFFF.)
@aschmitz it's also very important to not do what python does and interpret things like mathematical characters as the same as their non-mathematical counterparts. please don't do that.
it's been a while since i've looked at it in depth but i think the identifier syntax might be geared more towards things like URLs, where minimizing confusables is important, and not things like programming languages, where those distinctions are often relevant and important
