At this point, 'select foo()' means something different, and the user code is most likely broken (it's only safe if the code is 'select db.foo()'). With a warning printed when the SF is loaded (which has to occur before the call), the warning will provide a hint explaining the root cause of a later failure of 'select foo()'. With no warning printed, the user code will fail with no apparent reason.
