00:55 <havenwood> madprops: See the gist above, but block arguments don't stomp on local variable with each.

00:56 <madprops> "[:touched].each" that's interesting

00:56 <madprops> guess that works wtih :

00:57 <havenwood> I could make a better gist. The Symbol is just demponstrative.

00:57 <havenwood> demon*

00:57 <madprops> the symbol is a demon

00:58 <madprops> but yeah i get it

00:58 <madprops> it's like not using 'let' on a for loop in js

00:58 <madprops> doesn't confine it to scope

01:00 <adam12> https://github.com/seattlerb/hoe/blob/12474d92d764ac5244d2e60c5faed851fc58f042/lib/hoe.rb#L325 This is trippy.

01:00 <adam12> Does the symbol even serve any purpose pragmatically? or just make it read better? bizzare.

01:06 <ox1eef_> I don't think it has a purpose beyond explaining the logic of the code that follows.

01:06 <ox1eef_> It is unusual but I kind of like it.

01:06 <adam12> ox1eef_: I agree.

07:36 <ox1eef_> madprops: yeah, it is *kind of* like 'var' versus 'let', or 'const'. In Ruby though, 'for' does not have a block, so not quite the same. You will find if behaves the same, eg: if true; bar = 1; end; p bar # => 1.

07:37 <madprops> yeah

07:37 <madprops> i like that

07:37 <madprops> scrict scoping can be annoying to deal with

07:37 <madprops> strict

07:38 <ox1eef_> I'm not sure a huge fan of that, I'd like if to have its own scope but I've never saw it be an issue in practice either.
