Isn't there Puthon and JPython?

You are correct. I had forgotten about Jython (the successor to JPython -- I don't think there is any Puthon). In my view, Jython is a bit different -- it is Python written in Java. Kinda like Objective-J. At one point there used to be a PerlScript (from ActiveState) so one could use Perl syntax to write browser-side programs. My impression is that Perl6/Rakudo/Parrot nexus is qualitatively different from the Python/Jython nexus.

By the way, Occam was also correct.
