17:13 <FromGitter> <RespiteSage> Does stdlib have its own logic for type promotion when adding different numeric types, or does it rely on LLVM for that?

17:14 <FromGitter> <RespiteSage> In particular I'm thinking about the case of `a + b`, where `b` is a wider type than `a`.

17:14 <FromGitter> <RespiteSage> So like `Int8#+(UInt64)`, as an extreme example.

17:33 <FromGitter> <Daniel-Worrall> Int#+(otherInt) returns self class, so no

17:33 <FromGitter> <RespiteSage> No, that's not what I mean.

17:33 <FromGitter> <Daniel-Worrall> It'll raise overflow, not promote

17:33 <FromGitter> <RespiteSage> This is what I mean: https://carc.in/#/r/bid3

17:34 <FromGitter> <RespiteSage> Maybe "type promotion" was the wrong wording.

17:34 <FromGitter> <RespiteSage> Unless I'm sorely mistaken, the hardware doesn't do arithmetic on numbers of mismatched length, so either Crystal or LLVM has to turn those numbers into the same type under the covers.

17:35 <FromGitter> <RespiteSage> Presumably it's the larger type, and then they try to convert it to the left-hand type, which could raise overflow.

17:36 <FromGitter> <RespiteSage> I'm asking this because I'm trying to handle arithmetic with mismatched numeric types in saline (https://github.com/RespiteSage/saline).

17:50 <FromGitter> <RespiteSage> Okay, found it (https://github.com/crystal-lang/crystal/blob/dd40a2442fa186add8a82b74edb14a90aa1dae05/src/compiler/crystal/codegen/primitives.cr#L155)

19:13 <FromGitter> <Daniel-Worrall> yikes, my playground docker container was using 1.2GB of memory

20:58 <Guest15> hello all. i am wondering if variadic functions are supported for crystal functions and procs. ive tried playing around with VaList and viewing the specs around it, but i cant seem to make sense of it. does anyone happen to have an example of passing multiple arguments via variadic functions with crystal?

20:59 <FromGitter> <HertzDevil> crystal defs: https://crystal-lang.org/reference/syntax_and_semantics/splats_and_tuples.html

20:59 <FromGitter> <HertzDevil> c funs: no (crystal-lang/crystal#214)

20:59 <FromGitter> <HertzDevil> maybe you could use valist exactly like c i don't know
