Subject: proc/block with return


it seems that the semantics of return inside of a proc/block have changed
in subtle ways, but I can't really figure out what's going on.

I've seen it listed in http://dev.faeriemud.org/changes-1.8.0.html, but I
have trouble understanding what happened. I've looked a bit into
ChangeLog, like this:

grep -n5i return doc/ChangeLog-1.8.0 |grep -i proc

and found an entry like this:

Fri Jun 20 23:28:27 2003  Yukihiro Matsumoto  <matz@ruby-lang.org>

        * eval.c (proc_invoke): should not propagate TAG_BREAK and
          TAG_RETURN from orphan Proc object. [ruby-core:01148]



But I will please need some help to figure out the consequences of the
above log entry. I would like examples of how ruby 1.8 is different from
1.6, and what are similarly constructed cases that are _not_ different
from 1.6, so that I can have a precise idea of the change.

A pointer to sufficiently detailed documentation would be helpful too.
