At the time of creation function body could be parsed and referenced
objects stored in system table (or function could be marked as dirty
and referenced objects would stored at first compilation and after
each subsequent successful after-dirtied-compilation).
Isn't it possible for PL/_ANY_L_ too?

Sure.
