Re: set lvalue = rvalue

You are right, the expression evaluator has a couple of problems in
version 2.x, all of which are being corrected for 3.0. With any luck and a
lot of hard work, 3.0 will be out sometime this year (it's a complete
rewrite for the NetBeans Platform).

I'll see what can be done about back-porting the new expression evalutor
to 2.x; will be a bit of work since the new code uses Java 5 features.
