It would say "left paren" and "right paren." It's not terribly hard to keep a stack in your head of how many close parens you're expecting in some context. Manually managing brackets in long or deeply nested forms (in any language) is a pain whether you can see or not. As you said, pseudo-structural editing is a big advantage.
