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";

[choroba]: Low-end is defined as the Perl that generates millions of income
