Why would you need it?

This is unworkable --- consider a table with more than one unique
constraint and/or multiple-column constraints.
I seem to recall someone proposing extending the syntax of the UNIQUE
constraints themselves, but there really isn't enough use-case to
justify it AFAICS. Especially not when you can always use CREATE UNIQUE
INDEX.
