[lug] perl hash and array assignments in a loop

[Jeffrey Haemer]

Karl,

I think I'm already using one of your constructs


Nope, you're not.  That's why I gave you a working code sample that you
could cut, paste onto the command line, and see work.

Correct.  Pulling the array out of the quotes won't work.

You betcha.  I try to develop and test constructs as command-line one-liners
because I like quick feedback.
Of course, if I stopped making mistakes, I wouldn't need to, but I'm having
trouble with that.

 I'm starting to gather the whole scalar only concept of perl.


Perl isn't scalar-only.

Perl gives you a lot of flexibility of expression, which was what I was
trying to illustrate by including both a hard-to-read and an easier-to-read
form.  Looks like I didn't do a very good job. :-)

Perl's not for everybody or everything; however, I did, at least, want to
make sure you'd gotten what I sent because I'd thought it addressed and
solved the problems you were asking about.
