Hi

my new toy is urxvt which is a terminal emulator that can be extended with (yay) perl.

Skimming throught the documentation on how to write extensions I came across this piece of advice:

All of these hooks must return a boolean value.
...
When in doubt, return a false value (preferably "()").

I am a bit baffled as to why "()" should make a better false value as say "undef" but I am sure there is a reason for this.

Anyone with an idea?

Many thanks!
