Yes, I know. Hence the smiley.
Enforcing explicit datatype conversion would, however, have made it
clear right from the start where the problem was, just like it can make
all kinds of other bugs easier to find. Sometimes I wish I could turn
on type checking in perl with 'use stricter' or similar and have to do
all my own type conversions, in much the same way as taint mode forces
me to verify the safety of my inputs before doing anything dodgy with
them.
Currently hunting for a suspected bug at work, which we think is caused
by the difference between undef and 0. I'd love to have "type mismatch
at lib/Wibble/Boing.pm line 231" in the logs!

I caught myself pulling grey hairs out of my beard.
I'm definitely not going grey, but I am going vain.
