alias and extern(C) for callbacks

[Carl Sturtivant]

The D language page on interfacing to C
http://dlang.org/interfaceToC.html
says under 'Callbacks' that e.g.

   alias extern(C) int function(int, int) Callback;  // D code

is OK, so I am wondering if I can factor out the extern(C) from 
aliases as follows

   extern(C) {
     alias int function(int, int) Callback;
     // more aliases
   }

Is Callback here a name for the same type as if it was defined by 
the following?

   alias extern(C) int function(int, int) Callback;
