Sorry, I, kinda, misunderstood you suggestion before.
This is a really good implementation, but as you said, this function should,
and I quote from its description, "look through various unimportant
expressions". So I guess it is better to leave it this way (with the loop), as
it is already in the base code. What do you say?
