           Summary: Calling a function with an address of another function,

Sorry for the long summary.  In the following code,
the last line of main() is rejected by the compiler:

int function() wrap(void function()) {
  static int worker() {
    return 0;
  }
  return &worker;
}
void main() {
  auto x = wrap(&main)();       // OK
  wrap(&main)();        // found '&' when expecting ')'; no identifier for
declarator wrap; etc.
}

This seems to have to do something with an ampersand
('&') because similar code with passing other objects works:

  auto m = &main;
  wrap(m)();

compiles correctly.
