in reply to Tossing unwanted values from returned list

instead of wasting the trash scalar, you can use LHS undefs:

(undef, $foo, undef, undef, $bar) =(1..5); print "$foo $bar";
but in general, I will use split 'in parens with brackets' as you mentioned. It's pretty direct, you don't waste any characters dealing with elements that you're ignoring.
($foo, $bar) =(1..5)[1,4]; print "$foo $bar";

[james28909]: i dunno, if i didnt have so little experience in linux i would swap. but it would be to much of a learning curve for me right now.
[choroba]: Low-end is defined as the Perl that generates millions of income
[choroba]: sorry, that's high-end, of coursse
[choroba]: low end, in my talk, will be code that "we don't touch because it works" and noone knows why
[choroba]: I want to present the most bizzare bugs and misfeatures I met when working for a large financial institution
[choroba]: I already gave a similar talk to my friends in a pub and at an internal conference at work and people liked it, so maybe...
