Don't you want the regexp to be inherited when you descend
the hierarchy?

Regexp(2) uses longjmps, which are a bad idea in a threaded
world.  The original version of acme was in Alef, which doesn't
even have longjmp, so its regexp library used a threading
trick to manage errors.  It's actually a pretty trick that I was
happy to keep in the C version of acme; in fact, I used it in
several places.
