Sure. At the moment there is no reason for parse_func to think that
mydom is anything, right?

Something has to be done ;)

There could also be an explicit heuristic *after* the exact match
gathering to look for an exact match for domains reduced to their base
types. Is there any reason to look for domains before that?
