Feature request: Ruby lambdas

[firedev]

Hi,

It would be great if I could get rid of the old Ruby lambda syntax lambda { |x| } and convert:

lambda { |x| whatever(x) }

↓

->(x) { whatever(x) }

This is one-way transformation. But the next one should be reversible:

->(x) { whatever(x) }

↕

lambda do |x|
  whatever(x)
end

Please let me know what you think as this might be hard to make.

Sorry this should go to Switch.

It's kind of hard to say where it should go, because it would work in both cases :). There's actually an issue about this already, #65, but I'm starting to think it'll be a lot easier to implement this in terms of switch. I'll write more in the switch issue.

Since the issue was discussed in more detail in my switch plugin, I'll go ahead and close this one.
