Good! Because I wasn't ;)

Fixed.

Fixed.

You're actually doing it right, unless you wanted to instantiate the
wrapped MiniD class, in which case it'd be more like:
pushGlobal(t, "Foo"); // get the global class Foo
pushNull(t); // make room for 'this'
rawCall(t, -2, 1); // call the class to instantiate it (1 return
for the instance)
newGlobal(t, "myfoo"); // save it in the global myfoo

Fixed.

This code now works, just svn up your MiniD installation :)
