Not entirely true:

template muddle( T, U...){
  alias T delegate( U) Dptr; 
  auto muddle1( T, U...)( Dptr f) {
	return f; //or make another delegate in real code
  }
  alias muddle1!( T, U) muddle;
}

unittest {
	import std.stdio;
	int x = 3;
	int scale( int s) { return x * s; }
	auto f= muddle!( int, int)( &scale);
	writeln( f(7));
}
