This code doesn't work:
----------
//import std.typecons;
struct Typedef(T){
    T a;
    template opDispatch(string name) {
        static if (__traits(getOverloads, a, name).length != 0) { }
    }
}
struct A {}
void foo(Typedef!A a) {}

void main()
{
    Typedef!A a;
    a.foo();
}
-----------

$ dmd -run main
main.d(5): Error: function main.foo (Typedef!(A) a) is not callable using
argume
nt types (A)
main.d(5): Error: a.foo cannot be resolved
main.d(14): Error: template instance
main.Typedef!(A).Typedef.opDispatch!("foo")
 error instantiating
main.d(14): Error: function expected before (), not a.(__error) of type _error_

-----------

git bisect result:

   5d7ccff11d5bc91824bda7b66edca6318742f80b is the first bad commit

Reduced test case.

struct Typedef(T)
{
    template opDispatch(string name)
    {
        static assert(0);
    }
}

struct A {}
void foo(Typedef!A a) { assert(0); }

void main()
{
    Typedef!A a;
    a.foo();
}

For the later UFCS name lookup, the errors in opDispatch instantiation should be gagged.
