Moto 0.20.0 Release

	Moto 0.20.0 has been released and can be downloaded from 
http://www.projectmoto.org/download.moto. This release adds support for 
Operator Overloading in Moto! Overloaded operators may be declared in 
moto extensions and used inside Moto programs allowing programmers to 
write more compact, readable, and most importantly fun code! Perl 
programmers may now comfortably write foo["bar"] = "baz", while C++ 
purists enjoy the pleasure of intersecting sets with the * operator.

Instead of this:

Object o = stab.get("foo");
vector.put(27,"foo");

You can now write this:

Object o = stab["foo"];
vector[27] = "foo";

This release was developed almost entirely by Stefano Corsi! Be sure to 
send your thanks and rave reviews to him personally on the moto mailing 
lists!

To demonstrate this new feature many newly overloaded operators are 
included in the codex util extension.

Function lookup performance has also been dramatically improved leading 
to better performance in interpreted mode.

Here are the full release notes :
