mixins make the code more ugly and the error messages' line numbers will not be in sync with the code, IIRC.
I would like this syntax sugar too.

It's also used in GO, btw.

Diggory:  That's very cool -- being able to do that in D. Thanks for showing me :)

But it is not even a remotely practical solution.
   The idea is to write less, and so the solution you've given is to write more mixins all over the place. I said I don't even want to write 'auto', I am surely not writing the big mixin chunk.

I only gave an example of math stuff.
But I'd use := for the non-math stuff too.

I want := it to be available everywhere.
Even if I am just typing a snippet into dpaste.

If D implements this, C++ will try to copy it 10 years later.
It's a futuristic thing -- what is old is new.

The mixin definition only needs to exist once, and you can use "mixin" anywhere - you could wrap an entire source file in it:

mixin!q{

/* All of your code */

}

*mixin Math!q{ ... };
