   Yes, that is how I am trying to do this now; only I use Alternatives and
do

and_or = Alternatives("and", "or")
query = Alternatives()
and_or_func = Sequence(and_or, '(', Repeat(query, minCt=1), ')')
query.alternatives = [adapt(a, Rule) for a in Field("name"), cmp_expr, and_or_func]

   I'll try... but do not expect the patch too soon...

   Meanwhile, there is a bug in Repeat class: sepIsTerm was not defined,
but used; actually the variable mentioned only once in the file.
