Proc#== behaviour (from Ruby-Core)

[Note:  parts of this message were removed to make it a legal post.]

I did ask this question on Ruby-Core a few days ago, but no-one has replied
back, so I thought it might get more love here. (Perhaps I'm being stupid.)

I'll just copy it verbatim from there. If cross-posting it is wholly
objectional, I'm happy to wait, although this problem is holding up some of
my code.

I've encountered a problem when using Proc#== (with both lambdas and procs)
in my code, where the result does not match up with what the documentation
says. 1.9.2 differs from 1.8.7 in result and in the source code, so that
suggests attention has been given to the method, at least. It was suggested
that ruby-core was the place to go for this.

Here's a paste of the problem, with full RUBY_DESCRIPTIONs:
https://gist.github.com/899026

I've included lambda, proc, and Proc.new variants just for completion, even
though I realise proc is an alias for lambda or Proc.new, depending.

At the very least, perhaps someone could explain why this is by design, if
it's not a bug. Apologies if there's an open issue for this on redmine; the
site is currently not working for me (again), and I couldn't find anything
online mentioning this.
