You can do things like this though
% mkdir ab ac bc dc; () { touch $^@/{foo,bar} } ??
% echo ((ab|b?)/)#foo(e:'(( RANDOM < 16000 ))':)
ab/foo
% echo ((ab|b?)/)#foo(e:'(( RANDOM < 16000 ))':)
bc/foo

You just can't have a / inside a (foo|bar) group, which you do
potentially need sometimes. The pattern I used would also match
ab/bd/ab/bn/foo recursively.
