It was thus said that the Great Charles Heywood once stated:

Reread the pattern:
%?.-([^$][^$][^$])%$
So,
?123$ - matches, should return 123
?987654321$ - matches, should return 321
?12$ - no match, should return nil
?12$$ - no match, shoudl return nil
which means the LPeg pattern I gave is slightly incorrect. I'll fix it in
another message.
