The compiler doesn't seem to be able to infer the type for a delegate literal
which is used as an argument to a function template inside a class template.

struct Test(T) {
  void run(U)(U delegate(T) dg) {}
}

void main() {
  Test!string test;
  test.run((p) { return 12; });
  // test.run(p => 12); // This also fails
}


error : undefined identifier T, did you mean template to(T)?
error : template Test!(string).Test.run does not match any function template
declaration
error : template Test!(string).Test.run(U) cannot deduce template function from
argument types !()(void)
