Hi,
from my understanding UFCS is supposed to work with operator overloading.
I.e.
in the following a + b should work
struct Foo {}
Foo opBinary(string op)(Foo lhs, Foo rhs) if (op == "+")
{
return Foo.init;
}
unittest
{
Foo a, b;
a + b; // fails to compile
}
Is UFCS supposed to work with operator overloading, isn't it?

I don't know why that doesn't work (unless you just need to make it "auto c
= a + b;" so it isn't a "statement has no effect"?), but FWIW that's not an
example of UFCS. UFCS would mean calling your opBinary above like this:
a.opBinary!"+"(b)
Instead of this:
opBinary!"+"(a, b)
a + b => a.opBinary!"+"(b) => opBinary!"+"(a, b)
^ ^
standard rewrite UFCS
