           Summary: Type deduction fails with dependencies between
                    parameter types

This fails with the error: "undefined identifier T.Inner" in 2.063

void foo(T)(T x, T.Inner y) {}

struct Bar { alias int Inner; };

void main()
{
    foo(Bar(), 0);
}

Calling foo!Bar works.


I don't know if this is really a bug, or an enhancement request, but analogous
code works in C++:

template <typename T>
void foo(T x, typename T::Inner y) {}

struct Bar { typedef int Inner; };

int main()
{
    foo(Bar(), 0);
    return 0;
}
