This is not an issue.

If you want to merge overloads, you can add alias declaration to do it.

template T() {
  int m_attr;
  const {int attr() {return m_attr;}}
}
struct S {
  mixin T t;
  void attr(int n) {m_attr = n;}
  alias t.attr attr;    // Merge overloads
}
int main() {
  const S s;
  int r;
  r = s.attr();
  return r;
}
