It's also unnecessary. The Holy Scoping Rules actually work in your favour in
this case. In Perl 6 you can just do this:
while my $cond = blah() {
...
}
and C<$cond> is defined *outside* the block. So if Larry were to allow C<else>
on loops, you'd be able to write:
while my $cond = blah() {
...
}
else {
print $cond;
}
Given how rarely this kind of thing is actually needed (I've *never* used such
a construct), I suspect that an explicit variable is adequate.
