The "come from" was intended to be used * without * a corresponding goto,
so it would actually be a construct which would encourage really horrible,
disgusting, unstructured, <insert rude word here> core (oops, i meant code,
but core is probably appropriate too :-) ).

It has been implemented in some languages as a debugging tool---not to be
used in real code. Also, it has been implemented in INTERCAL, a joke
language, which encourages programming worse than found in the Obfuscated
C Programming Contest.

But the way you propose it, it sounds actually very nice.
