Yes. The Preelaborate rules only apply at library level, and a procedure is
not library level by definition.
One cannot declare a preelaborable bounded string constant, as the
initialization will necessarily fail the preelaboration checks.
I recently worked out a proposal that could have changed that, but it became
way too complex and it went nowhere. (Recall the similar discussion here
about having a preelaborable constant of type Address.)
