Witam.
Robie drugie podejscie do nauki perla wiedc prosze o wyrozumialosc.
Problem jest taki - dlaczego dziala to:

perl -e '@l=qw/los sol wod/;foreach (@l){print if /lo/}'

a nie dziala to:

perl -e '@l=qw/los sol wod/;foreach $item (@l){print $item if /lo/}'

W ksiazce mam podstawowa definicje petli foreach wlasnie w tej drugiej
postaci.
Z gory dzieki i pozdrawiam.
TJ
