The dis module is deliberately (*) not part of the Python language and
standard library; it's an implementation detail (as is the func_code
attribute, and the code object).

So the question really is: can you tell the difference, using only
mechanisms not explicitly documented as implementation-specific?

(*) Unfortunately, the documentation fails to mention that, probably
because it's too obvious.
