; This example is similar to the code that the following Verilog program
; would generate:
;
;    module main;
;       reg a;
;       wire b = a;
;       initial begin
;          a = 0;
;          #1 $display("a=%b, b=%b", a, b);
;          a = 1;
;          #1 $display("a=%b, b=%b", a, b);
;       end
;    endmodule
;
; This tests that a simple continuous assign of a net from a var works
; properly. This is a very trivial functor propagation that is initiated
; by the %set instruction.
