Do you mean that it should match the the patterns in the order they
occur in the file, returning the first type that matches?  Does
=tagging-method do that now?

Another thing to wonder about for concatenation is whether rx can
optimize the resulting expressions, in particular, whether it can factor
the trailing `$' out of the or-expression (if not, it would be simple
enough to heuristically optimize a few simple cases resulting from
concatenation before calling rx).
