Yup. Functions are functions.

Perhaps. We have resisted adding a separate "CALL" type of command,
though, as long as it would only be syntactic sugar for calling the same
kind of function object. There has been a lot of discussion about
adding a different sort of stored procedure that would execute "outside"
rather than "within" the transaction engine, so that it could start and
commit multiple transactions; and if and when that happens, it would
need a different type of statement to call it.
