2022-04-12 14:08 jhass[m] changed the topic of #ruby to: Rules: https://ruby-community.com | Ruby 3.1.2, 3.0.4, 2.7.6: https://www.ruby-lang.org | Paste 4+ lines to: https://gist.github.com | Books: https://goo.gl/wpGhoQ

00:09 <leftylink> pandabot: rb class Foo; def self.bar(x) "bar #{x}" end end; def doit(&f) f[5] end; doit(&Foo.method(:bar))

00:09 <pandabot> "bar 5" - https://carc.in/#/r/dhc0

00:09 <leftylink> hopefully the working example can be used to compare against the non-working example, and the differences can reveal why it isn't working.

00:12 <leftylink> I gues it's not a 100% faithful reproduction of the questoin as asked though, so I'll make a more faithful reproduction

00:12 <leftylink> pandabot: rb class Foo; def self.bar(x) "bar #{x}" end end; def doit(y, &f) f[y] end; doit(5, &Foo.method(:bar))

00:12 <pandabot> "bar 5" - https://carc.in/#/r/dhc1

00:12 <leftylink> okay, that should be faithful to the question

04:55 <tsujp> Well seasoned Rubyists. I'm looking to make a little language inspired by Ruby's syntax. What are some (non-super-obscure) quirks about Ruby's syntax you might share with me that you wish weren't so?

07:26 <jhass[m]> constructs which are the same except for the precedence (&& and `and`). Just pick one

07:27 <jhass[m]> not quite syntax, but non-global globals (`$~`), just work with return values

07:28 jpn has joined #ruby

07:28 <jhass[m]> Nobody actually needs the flip-flop operator or regex capture group to local variable promotion (again on the blurry line between feature and syntax, I realize)

07:29 <jhass[m]> I don't know, probably a lot of similar things. Check Crystal, they've gone this path before. https://github.com/crystal-lang/crystal/wiki/Crystal-for-Rubyists

07:30 <jhass[m]> some of these differences are due to limitations in a compiled environment, but some are also cleaning up ambiguity within Ruby
