Bug 10228 – 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; }
