Looks like this has been fixed. All programs in this page compiles for me. 


struct Foo {
double x, y;

ref double get(Args...)(Args args) if (args.length == 4) {
return x;
}
}
void main() {
Foo f;
f.get(4,5,6,7) = 6;
assert(f.x == 6);
}


Can we fix this std.complex bug then?

Some operators, such as opAssign and opOpAssign, should return by ref, but
currently don't. This will be implemented as soon as DMD bug 2460 is fixed.

Today, I hit the similar problem.

In the latest dmd, above code works but variadic version doesn't works.

struct Foo
{
// works! I use this for workaround
template foo(Args...) if (true)
{
ref Foo foo(Args args)
{
return this;
}
}

// doesn't work. I want use this!!
ref Foo foo(Args...)(Args args) if (true)
{
return this;
}

// works!
ref Foo foo(Args...)(Args args)
{
return this;
}
}

Raising importance, since operator overloading is now done with templated
functions, and this will become a major pain in the long run.
