"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.
While you're technically correct, every major compiler in the unix world support it with the same
syntax. It's entered into defacto standard status.
