Wild idea.
When I was a newbie, I repeatedly make the mistake of writing
alist = alist.sort()
I suggest a singleton object "UseForbidden" ("Py_UseForbidden" in C).
"UseForbidden" can be used only to return from a function. Any other
attempt to use "UseForbidden" raises an exception. The incorrect code
above would give the error message "cannot assign to result of function".
