He did not forget it. It is just a completely dumb idea for a feature
that I'm sure it never even came close to entering his mind.
If you REALLY must abort from deep inside nested loops (or recursion),
without using a boolean flag value to control the continued looping (or
recursion), you could raise an exception (an of course catch it outside
all the loops (or recursion).
