Hi Shweta,
I already asked it (the mail is attached). But I did not get any reply 
on that.

attached mail follows:

Hi,
Is base class of a class declaration allowed to be forward referenced? 
Is the following case valid?

module top;
typedef class bas;
class der extends bas;
endclass
class bas;
endclass
endmodule

Most of the simulators fail for that. But I did not see any restriction 
inside LRM. If it is allowed, then I am little bit curious on the 
following case:

module top;
chandle x;
typedef class bas;
class der extends bas;
   function new;
       x = 1;
   endfunction
endclass
class bas;
   int x;
endclass
endmodule

What 'x' will be referred for function 'new', is it 'chandle' or 'int'?
