Subject: RCR: $INCLUDED global var

$INCLUDED = (__FILE__ != $0)

Just because "if !$INCLUDED" would read so much better than "if
__FILE__ == $0"

(Just googled, and this has come up before - ruby-talk 21504. However,
no one came up with a really convincing name, so I think the thread's
worth reprising).
