I have to admit I'm having a hard time understanding why you'd need to 
test the undecorated functions.  After all, the undecorated functions 
aren't available to anyone.  All that matters is how they behave with 
the decorators.

But my imagination is weak: do you mind explaining more about what the 
functions do, what the decorators do, and why you need to test the 
undecorated functions?  I'll learn something, and with more information, 
we might be able to find a better solution.
