I think I haven't communicated my desired feature clearly.
I am not asking perl to divine anything about run-time availability of
definitions. I explicitly don't want to rely on dynamically defined
subs.
All I am asking for is this: I want perl *not* to "hope" that a
definition will be available at the time of invoking a subroutine.
I want perl to tell me up front, if the code that it received for
compilation is missing a sub definition.
When perl is done with all its compilation, juuuuuust before starting
execution of the compiled code, it should verify that every invoked
subroutine has a definition. If a definition is missing, perl should
immediately die with a suitable error message. I don't need this check
to happen as soon as the invocation is seen by the compiler. I only
need it to happen after all compilation is complete.

I cannot phrase my point any better than the previous time around.
So I'll pretty much repeat myself.
The user is asking perl to flag some *legal* usage as being
unacceptable for her/his purpose. This is no different from any other
stricture.
If it means that the pragma is incompatible with many extant modules,
that is life. "use 5.008" is presumably incompatible with many
modules, too.
