'I'
>>> inn = inter('am')
So, we see that a func_closure property is a tuple of closure cells, we can refer them and their co...

g++ -o main.out main.o c.o
./main.out
Without extern "C" the link fails with:
main.cpp:6: undefined reference to `f()'
because g++ expects to find a mangled f, which gcc did not pro...
