	I cannot find any stmt in LRM saying that the initialization
order should be the same as declaration order - should it be
implementation dependend, or this just similar to race condition and the
order is undefined by purpose? SV allows static varialbe to be
initialized with nonconstants - so this became an issue.
	Consider the example:
	 
	class C;   
	 int p;
	    function integer random4val;
	        return p;
	    endfunction
	endclass
	 
	module top;
	    C c = new;
	    
	    integer nc8 = c.random4val();//if initialization order
should be the sam as delcaration order - then ok, but if it is undefined
then null pointer exeption may occur. What about case when change the
order of c and nc8 declaration?
	        
	    initial begin       
	        $display("%0b", nc8);
	    end
	    
	endmodule
