Jebuz, Tim, of all the people in the universe, I wouldn't have expected
pedantry from you.
perldoc -f length
length EXPR
length Returns the length in characters of the value of
EXPR. If EXPR is omitted, returns length of $_.
Note that this cannot be used on an entire array or
hash to find out how many elements these have. For
that, use "scalar @array" and "scalar keys %hash"
respectively.
Works for me, every time.

Really? Please explain. What's %length EXPR, if not just a typo
for length EXPR?
