"4. If a and b is a struct or class object reference, it is an error. "

If so do you plan on making class by class operations overloadable in a

Can you add an example for 4.?

Very good!  Now, on to the op= operators...since they are often much
faster and memory efficient to implement :)

In fact, in my mathematical classes in C++, I would often implement op
as derived from op= .  I would create a temporary copy of an object, use
the op= function on that, and then return the temporary...

I believe that adds significant complexity to the language, whereas the
naming convention route offers equivalent power (or even more power, as the
functions can be virtual, variadic, etc.) very simply.

Yes, that one had me stumped for a while.

I agree, but since the desired result can be adequately addressed with the
member syntax, I thought adding more syntax for global functions was not
worth the cost.

This is the latest version used by WinD, and it's hand-coded (unlike my old

Sorry about that, I kept reading this line from the Structs documentation:

 ...So one could define :+: to add
matrices, etc., and as these would really be functions, they should
follow the normal overloading rules of functions.

This would allow them to be easily parsed, would distinguish them
clearly from the standard operators, and would provide the majority of
the notational compactness that normal operators provide.  The fact that
A :+: B would be syntactic sugar for A.add (B) is minor, but convenient.
   As to precedence ... they should probably bind more strongly than any
other operator, and all to the same degree.  If you want to get fancy,
you'ld need to use parentheses.


 Now this idea has a lot of merit! Thanks for posting it. I *like* it being
 clearly distinguishable from the native operators.

Ah, the ghost of postings past <g>.

I was wrong. The trouble with :+: being for overloaded operators and + for
builtin operators is that generic templates don't work. It has to be the

There are different keyboard mappings, and many OSes allow you to create your 
own - so one could 
create such a mapping, for example I could do it for BeOS, and then just 
switch back and forth.
Then the only problem would be to remember which key corresponds to which 
operator.
