Well it would seem very messy coming from Scheme!

Scheme is a small language which achieves expressiveness by allowing you great freedom to push the language into bold new forms.

Ruby (especially with Rails which should almost be considered a separate language) is a big language where simplicity is maintained by informal convention.

Ruby has lots of muddles and messy features, good Ruby code bypasses them.

Ruby was among the first languages I learned, back when there was the possibility of Ruby being a general purpose language and not just Rails. My joy was the result of being able to guess syntax and be right. Nowadays I value reading documentation and IDE level support, so guessing syntax is no longer a joy.

When I saw it, I felt the same way (also using Scheme a lot) and I still feel it is messy. However, what I think might be the reason for it, is that it is difficult to store a lambda in Scheme including its whole environment in an object and send that over the wire somewhere else, on a different machine to run. Perhaps distinguishing between Proc, block and lambda gives Ruby a possibility to treat one of them specially, so that it can do these things easily?

I can gladly point out that Crystal has a much cleaned up syntax for blocks and procs (compared to Ruby): https://crystal-lang.org/reference/1.5/syntax_and_semantics/...

> Personally, I thought the muddled Proc, block, and lambda situation a mess

Why not use one (probably just block) for everything? Coming from ruby 10 years ago.

I guess those things are a compromise. Being able to use that concept easily is a joy. The implementation prioritises developer convenience over syntactic purity. It’s a shame we can’t have both, but I accept the trade-off.

That's quite a minor nitpick on an entire language that's been around for over 25 years.

What about it makes you cringe?
