Interesting discussion, I am not convinced of the value yet, but then again most of my
experience is in Perl and so wouldn't have really thought to do it, so always open to
something new...
No one has mentioned 'eval' that I have seen in this little discussion, couldn't it be
used to wrap the while loop so that it would appear to return a value to be caught?
my $return;
$return = eval { while ( ) { } };
Of course then you deal with compile/runtime issues, checking $@, etc.
