RE: [sv-bc] Function call without ()

Adding in the SV-EC regarding http://www.eda-stds.org/sv-bc/hm/9007.html
.  Some relevant sections in draft 7a are 13.5.5 ("Optional argument
list"), 13.7 ("Task and function names"), and 23.8 ("Upwards name
referencing").

-----Original Message-----

But if a class method even called as forward referenced inside the class

without argument, is it an error or not. Normally a function can be 
forward referenced. LRM is silent on that. Please consider the case and 
let me know whether it is correct or not:

module top;
class C;
task t;
int x;
x = f; // Here 'f' is a class method declared later.
endtask
static function int f;
return 1;
endfunction
endclass
endmodule

Surya
