Subject: calling break in proc

Hello,

It looks like a recent change has been introduced to the 1.8 branch in 
cvs and also to cvs HEAD that causes the following code to break:

----------------------------------
hash = { 1 => 'a', 2 => 'b' }

callback = proc { break }

hash.each(&callback)

==> LocalJumpError: break from proc-closure

However, the following does still work:

hash.each { break }

----------------------------------

The code works with ruby 1.8.1, but not with 1.8-cvs or 1.9.

Is this change intentional?  If so, can someone recommend a better way 
to exit early from a Proc object?  The catch/throw approach doesn't feel 
very natural.

Thanks,
Brad
