"Recently" the Python C interpreter was modified and speed up thanks to

I don't think there's any question as to the usefulness (and essentialness) of
this feature. I'm very close to just writing most of the interpreter in C over a
triviality like this.
To be pedantic, C and C++ don't have that feature. Some compilers add it as an
extension.
Also, such a construct could not be made @safe. The trouble is you could pass
those addresses anywhere, and goto them from anywhere.
