Absolutely. ref() tries to answer 3 questions - is it a ref, what's the
reftype, what's the class. It only answers the first one reliably and even
then there's a weird edge case. Getting the correct answer to the other 2
requires fiddliness.
If the other 2 questions were worth answering in the core then surely they're
worth answering clearly.

All good except could this cause problem if something found a REGEX in
*{foo}{SCALAR}?
