01:32 <FromGitter> <Blacksmoke16> @jgaskins Oh, https://github.com/Homebrew/homebrew-core/commit/5e8eaa529e036b33ddfb2faf84403280ec01cd12 homebrew maintainor updated it which added the bottle

14:29 <FromGitter> <nanobowers> This is probably a dumb question, but i'm unclear how the stdlib works re: `#to_s`: ⏎ ⏎ I'm poking at redefining `inspect` for Tuple, which calls `to_s`. to_s takes an IO param, but inspect never passes it in. https://github.com/crystal-lang/crystal/blob/6d9a1d5830db5f276bf3df37fceeb0d5333e7e14/src/tuple.cr#L430 ⏎ when i redefine inspect to call basically the same function, it doesnt work, so feels

14:29 <FromGitter> ... like there is some magic here that i'm missing. example at: https://carc.in/#/r/c226 [https://gitter.im/crystal-lang/crystal?at=616ae1b8d78911028ae0b24b]

14:30 <FromGitter> <nanobowers> I suppose the crux is that `#inspect` is not explicitly passing an IO object to `#to_s`, so it must be implied from somewhere else

14:30 <FromGitter> <Blacksmoke16> you need to define `def inspect(io : IO) : Nil`

14:31 <FromGitter> <Blacksmoke16> same thing with `to_s`

14:37 <FromGitter> <nanobowers> I think the key is that there was some inheritance in `Object` for the arg-less version of to_s, etc..

14:38 <FromGitter> <Blacksmoke16> the argless versions call the IO versions

14:39 <FromGitter> <Blacksmoke16> of which if you dont override it'll use the inherited version, thus you still see the default output

14:42 <FromGitter> <nanobowers> is there a way to do a `responds_to?` with a particular argument signature?
