I don't think anybody is claiming proprietary rights on Python
proper, i.e., the *language*? Copyright on the implementation,
and maybe trademark on the name in certain contexts. But if
you reimplemented the language independently (e.g. the way
Mr Skaller did with Vyper), deliberately "cloning" it, would you
be running any legal risk...? I thought only Java and ADA were
popular languages undergoing that level of 'protection'.
It's easy to get confused between a language and its implementation
when there's only one of the latter, but, with JPython, CPython, and
Vyper, not to mention forthcoming developments such as Python.NET,
it doesn't seem to me that this is the case. Or are all of these
versions derived works of CNRI's-claimed stuff? I thought Vyper
at least wasn't (it's got its own license, LGPL, but, again, only on
the _implementation_, I think...? i.e., not on the language being
implemented -- much like, say, gcc, MS's VC++, etc, each have
their intellectual-property claims, but none claims to own _C++_
