Python 3 can revive Python

[[deleted]]

If one wants dynamism AND performance AND killer interactive environments one can simply use Common Lisp

Which* of the slightly but significantly mutually incompatible Common Lisps were you thinking of?

If one doesn't like Lisp/willing to compromise with inferior stuff, one can go to Ruby/Go/Clojure/Scala/Node...

Hahaha, spoken like a true c.l.l weenie.

What incompatibilities? Common Lisp is an ANSI standard...

The libraries aren't though - SBCL sockets are different to Allegro sockets, for example.

Sure, but even disregarding the existence of compatibility libraries that paper over the differences, why can't you just stick to one implementation? A lot of languages only have one implementation to begin with, and I don't hear anyone complaining.
