 import std.stdio;
 import std.traits;
 
 int foo(int x, long y);
 
 void Bar(R, P...)(R function(P))
 {
 writeln(return type is , typeid(R));
 writeln(parameter types are , typeid(P));
 }
 
 void main()
 {
 Bar(foo);
 }
 
 
 // compiles but does not link in windows

A function pointer foo should point actual function body code. But foo does
not have body. Therefore it fails to link.

Supplying body code to foo will fix the issue.

int foo(int x, long y) { return 0; }

 the code came the tuple page on this web site.

Note that, D supports separate compilation model. `int foo(int x, int y);` is a
function declaration without its definition (== function body code), similar
to:

// A C lib function declaration
extern(C) int printf(const char* fmt, ...);

So it's not a mistake in the example code is.
