Can be written chomp(my $line = <STDIN>); ;D

But that doesn't generalise for all rvalue uses. For example, I frequently want to write something like

frobnicate(chomp) while <$file>;     # doesn't work

and am of course instead forced to write the loop out longhand, since

chomp, frobnicate($_) while <$file>; # yuck

is starting to get hard to read.

Personally I consider this a failure in Perl's Huffman coding. I can't think of a single case where I've cared in the slightest how many characters chomp removed, but I do want to be able to chomp something and then immediately pass the chomped value to some other routine.

    I think the point is efficiency (avoid copying the argument) rather than counting characters.
