Hi all,

Someone has links to examples of operator overloading in D? I read the
specification, but I was not able to understand it correctly.

I noticed that D doesn't have the operator keyword. I think that this 
keyword gives more flexibility and power than the simple use of functions
(opCmp, opEquals etc). IMHO, it should be added in D.

Thanks,

Bruno.

There is an opAssign function, to overload the operator '=' ?

No. It was decided (rightly, I think) that the semantics of the '=' 
operator on classes are ambiguous, so you have to explicitly copy your 
class with a method.

I have to confess I do not understand what was wrong with the C++ 
syntax. I find it oakward to type "opAddAssign" rather than "+=". 
Eventually the compiler calls opAddAsign when it reaches +=; what is the 
benefit of such a name discrepancy?

Sorry I may not get the point but as far as I understand, this D 
operator replacement achieves exactly the same as C++. Why changing 
things when there is no additional benefit? Just to give D an identity?

Rather then having to write some 24 overloads, in D you only need to 
write 8 to archive the same thing.  Something like that anyway.

As I spoke before, this has pros and cons. This facilitates the programming,
but removes a little of the flexibility (and elegance, I think) of the
language. But it is just my opinion, as a C++ fanatic :)

Yeah, it's just a C++ withdrawal symptom that a lot of people in the 
group seem to get.

Actually, giving the operator overloading a name gives it more flexibility,
greppability, and elegance. For a small example, consider ++ as a
preincrement and a postincrement operator. For a more significant example,
how would one do a generalized compare function that will work for <, <=, >=
and > of one were restricted to using the various comparison symbols?
