Thank you for these perl 1 liners juggling!

Why not adding an alternative to:
perl -le 'print~~grep/./,'

as another template example?...

perl -le 'print"TOTAL NON EMPTY LINES",~~grep!/^$/,'

It illustrates the negative regex and expands the alternatives a little further, just by using your examples.

Thank's
alberto
