Request: Subroutines could support arguments

[joshgoebel]

Presently (best way I know how):

      : local "a";
      : local "b" ;
      : set_integer var = "a"  value = "1" ;
      : set_integer var = "b"  value = "5" ;
      : gosub "add";
      : print (result_int);

subroutines {
   add : subroutine {
      : set_integer var = "result_int"  value -> (a+b) ;
   }  
}

Proposal:

      : gosub "add" a="1" b="5";
      : print (result_int);

subroutines {
   add : subroutine {
      : arg_integer var = "a";
      : arg_integer var = "b";
      : set_integer var = "result_int"  value -> (a+b) ;
   }  
}

Since subroutines are known at compile time the arguments to gosub also should be easy enough to evaluate at compile time... though this might require a quick second pass (not sure how the compiler works now)...
