I think the problem is the introspection method done in always_comb.

func.func_globals.items() just returns the wrong thing under doctest 
when there is a break in the code and no amount of playing around seems 
to solve this.

I've implemented a workaround in which mux_1 and the signals are created 
directly below the Mux code, these are then used in the test bench. I 
think it's pretty good and doesn't substantially detract from the 
information presentation.

Cheers,
