 I meant, could you store a compiled RE in a variable and use the
compiled form.  Then manually recompile them if someone changes the
uncompiled RE string.  This assumes you can store the compiled RE and
that there is a hook in custom to let you know it has changed.  We'd
probably want to have a function the regenerates all of org's REs and
allow others to hook into that to recompile their own REs.

 On the other hand, I just went digging through the elisp manual and
I didn't see anything that would generate a compiled RE to be stored
and (re)used later.  Bummer.  Maybe if I get bored, I might see if
performance is ok with the REs factored out, but I don't suspect I
would get good results.
