Subject: cool tricks for inserting element into array?
I'd like to turn array @tmp from:
(1,2,3)
to
(1,"|",2,"|",3)
I'm using:
@tmp = split(' ', join(" | ", @tmp));
... but it seems like a waste to create a string and then split it back up
again.
As a sidenote, are questions like this appropriate for the list? I really
don't *need* help with this, I was just hoping to expand my personal toolbox
with a better way to do something. Every time John, Wiggins, Luke, Bob,
Jeff, etc. respond to my emails I know I'm going to learn something.

Not sure if this helps but ...
perl -e '@tmp=(1..4); @tmp = map {$_, "|"} @tmp; print "@tmp";'
