( #3333=superdoc: print w/ replies, xml ) Need Help??

This was a good exercise. My biggest hurdle was figuring out why $_ held the value 2 and @_ contained qw(nothing nothing) rather than qw(alpha omega). After a bit of searching I think I found the answer.

I tracked down information on the qw operator and found this in the perlop manpage:

qw// is exactly equivalent to split(' ', q/STRING/); This equivalency means that if used in scalar context, you'll get split's (unfortunate) scalar context behavior...

So read the documentation on split and found:

If not in list context, returns the number of fields found and splits into the @_ array.

So is that pretty much answer? Is there any more magic to it?
