If you want to see grep really shine, though, think about ways you

I think that's very misleading. Why should I want to avoid calling print
for each element? What you've written is the sort of thing for which
Perl gets a bad name - it's less readable and has no obvious benefits
over
print "$_\n" foreach grep { $_ % 2 == 0 } @list;
(It also doesn't print a terminating "\n")
