Is this supposed to work? If the answer is negative, maybe it's a good idea to
support this:


struct Foo(T) {}
void bar(Spam, T)(Spam!T y) {}
void main() {
    Foo!int x;
    bar(x);
}


DMD 2.061alpha gives:

temp.d(5): Error: template temp.bar does not match any function template
declaration
temp.d(5): Error: template temp.bar(Spam,T) cannot deduce template function
from argument types !()(Foo!(int))
