//////////// test.d ///////////
class A     { int i; }
class B : A { int j; }

template copy(alias a, alias b)
{
    void copy() { a = b; }
}

class C : B
{
    alias copyIJ = copy!(i, j);
}
///////////////////////////////

Error:
test.d(11): Error: template instance copy!(i, j) copy!(i, j) is nested in both
A and B

The template should be nested in the descendant type.
