Thanks. While we are on it optimizing, does it make sense to make this a
c function? You can probably tell more about the overhead of condition-case?

However I think `buffer-local-boundp` is really only performance
critical in this single predicate in `describe-variable`. I cannot think
of another use case iterating over thousands of symbols and checking for
bound variables. So probably we are good now.
