Subject: Re: block returns and hash element returns

#next, of course! Thank you.

Okay, so use #next in place of #local_return.

  h1 = { :a => 1, :b => 2, :c => 3 }
  h2 = h1.collect { |k,v| next k => v*2 }
  h2 => { :a => 2, :b => 4, :c => 6 }

Could do this by modifying collect to merge hashes if they are the
yield result, but that's not exactly the same. since it would make it
impossible to collect hashes, and it would have not advantage over the
#graph method either --just substituting a hash for the array.
