Let's assume that the decorator wraps the function in a way that the 
wrapper has a reference to the original function, so it does not disappear.

The easiest thing would be to have the decorator add the original 
function as an attribute .wrapped to the wrapper. Then test foo.wrapped. 
If you do not like this 'special stuff', then you would have to 
introspect the wrapper to access the wrapped function. How to do that 
depends on the wrapper.
