I wish D templates could accept operators/functions as parameters.




  

It can accept functions as parameters - both as function pointers, 

 and as
aliases.



  

Let me get this straight.  What is the syntax?  I tried this:

template tempT(alias func)
{     void temp()
   {         func();
   }
   }


void myfunc()
{     }

alias tempT!(myfunc).temp() foo;

int main( char[][] args ) {
   foo();

   return 0;
}





  

 Cool, now for operators....


  


 You can use the equivalent name for the operator functions.

How could you pass in the operator for say - integers then?

use:
    alias tempT!(myfunc).temp foo;

Unfortunately, there's a bug preventing that from working, which will be
fixed in the next update.

 int main( char[][] args ) {
    foo();

If class Foo has an opAdd() function, use an alias parameter for Foo.opAdd.

Yeah I tried that as well.
