Prashant Deva built a Mantra plug-in for Eclipse that does syntax highlighting and such for Mantra. Portions of the code are Eclipse EPL licensed; rest written by Prashant.

I realized that we need the notion of a tuple like Python. List [1,2] is fundamentally an ordered thing not an aggregate of two elements. A tuple (1,2) treats those as separate elements whereas I can think of the list as one thing if I pass it to a function. A tuple is not accessed like a list and really is used to only hold multiple values. I could use this for parallel assignment, but I don't have that and I'm not sure I want it....

You can now refer to any regular Java object from within mantra simply by using a variant on the import statement:

import java java.util.Vector;

Vector v = Vector();
v.add("hi");
v.add(34);
println(v.toString());
println(v.get(0));
println(v.get(1));

Field access works as well for now, it translates only string and integer objects to mantra objects. For other objects, it leads them as Java objects wrapped in a JavaProxyObject.

imports allowed with main programs / scripts now.

import a::b;
println("hi");

added for-each construct.

Getting enough downloads of Mantra now that I decided to create the wiki and use it as primary documentation etc...
