japhy,
Thanks - which is why I said this deserved an entry in "Perl Idioms Explained". I could argue that there is no assignment going on in: 
while ( @array ) { ... }
# or
print "Array is empty\n" if ! @array;

but then we could discuss the difference between lists and arrays and it wouldn't be worth it. I think I was able to get the OP to understand even if I wasn't completely accurate. I do think it would make for a good entry in "Perl Idioms Explained".

Cheers - L~R
