This appears to have been the expectation of the Ada-83 designers, but
few if any compilers did so automatically (some had pragmata to allow
the developer to indicate that a task was really a monitor), which is
why protected objects were added to Ada 95.
Nevertheless, I would still prefer the use of a task to a semaphore when
mutual exclusion is needed for processing that cannot be in a protected
object.
