[FWP] From "The Art of Perl", Ch. 1

[Jeff Pinyan <jeffp@crusoe.net>]

I'm looking for some idioms for dealing with arrays, hashes, and unnamed
lists.  For more information on "The Art of Perl", visit:

	http://magneton-59.dynamic.rpi.edu/book/

Submissions I incorporate will be acknowledged.


Operating on Lists
------------------

array-to-hash

	while (($k,$v) = each %{{ @list }}){ ... }
	while ($i < @list){ ($k,$v) = @list[$i++,$i++]; ... }

slicing

	@list = (somefunc())[1,4,6..9];

hash things

	@uniq{@list} = ();
	keys %{{ @tmp{@list} = () or %tmp }};


I'd like some more ideas for idioms.  Some of them might be ones no one
else has seen (I doubt anyone has used that last idiom I put up there).
There are many commonly known ones that I've not put up on this list, but
mention them as well, just in case.

If this isn't a suitable application of the FWP forum, let me know.  I
thought some of these idioms, and the task of finding/making ones would be
fun... with Perl.
