in reply to Trouble getting size of list returned from sub

this can also work:

my $n = () = bad(); print $n; #print 4 sub bad { return qw/foo bar baz timon/; }

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

    You can also fold the variable into the same line as the print:

    say ( my $mp =()= bad() );

    But I wouldn't say that's an improvement. In fact, I would tuck all this away into a routine, to hide details and leave only the high-level purpose.

    To learn more about this ( the goatse operator ) and other fun, little-known operators, check out secret perl operators

    As Occam said: Entia non sunt multiplicanda praeter necessitatem.
