This issue causes major issues with Nd-array and Small Vector implementations,
as the incorrect type signatures play havoc with other templated functions.
Here is another test case illustrating the problem:

import std.stdio;
struct Matrix(T,size_t D) {
    Matrix!(U,D) foo(U)(U v) { return Matrix!(U,D)(); }
}

void main() {
    real r;
    size_t d = 2;
    Matrix!(float,2) m;
    writeln(typeof( m.foo(r) ).stringof);            //writes Matrix(float,D)
    Matrix!(float,d) n;
    writeln(typeof( n ).stringof);                   //writes Matrix(float,d)
}
