You're confusing "the func_name attribute of the function object" with 
"one of the names to which the function object is bound".

If you want to be able to invoke the-function-formerly-known-as-g using 
the name 'f', you don't want to change the func_name attribute, you want 
to add 'f' as a name bound to the function object.  In Python, name 
binding is accomplished through the assignment statement:

py> f = g
py> f()
decorating
this is in function g

What is is you're actually trying to do here?
