Hello,
I seem to have a problem when I use a template mixin and then try
to overload operators both in the mixin and in a struct from
where it's instantiated.
So the idea is that I have a few operators defined in the mixin,
then a few more in the struct, and I want to forward all
operations n

Can you elaborate. I don't see the duplication.

First we check that parameter is one of allowed ones in
constraint. Then we do the very same check using the very same
operator list to actually make a right dispatch. Looks

I forgot to mention that template constraints take part in choosing the
implementation as well:
void foo(string s)()
if ((s == "hello") || (s == "goodbye
Hm, but why can't static assert provide an instantiation trace? I
can live without error message but duplicating same condition
twice (one time being part of implementation) hurts my eyes :(

Agreed but t
Do you want to discuss it? :) I have noticed that phobos style
guidelines favor constraints heavily over static asserts but this
exactly the example when I am uneasy about such choice: static
assert can both provide more user-friendly error message here and
remove some code duplication.

Nathan M. Swan:
The correct keyword is "opBinary", not "opbinary".
The compiler must give an error message easy to understand in
similar wrong cases.
