Re: Java operator overloading

[Maya Gokhale <maya@lanl.gov>]

Hi Feng,
   It is somewhat related, but not completely. We want to do operator
overloading as in C++, so that, for example, an infix "a + b" will invoke
a particular method in "a"'s class that understands "+" given an argument 
of "b"'s class. This is the opposite of "boxing" which converts 
primitives into objects. We want to allow user-defined objects to 
overload builtin operators.
   For our applications it would be convenient to define new sorts of
integers, fixed point, and floating point numbers and use infix operators
on them. I think Java Grande might be looking at that sort of thing, but I
couldn't find an implementation.

Thanks,

Maya
