I habitually use single quotes for one-liners, so I always get caught
out if I have the misfortune to be using Windows' excuse for a shell, in
which the only quote character is "

> perl -le 'print "Hello World"'
Can't find string terminator "'" anywhere before EOF at -e line 1.

Quite annoying, but at least you don't have to worry about variable
expansion most of the time as it's impossible (AFAIK) to escape it in
any way.
