Good point.  In general this is true because we have
these "transitional" values, so yes.

At some point you would want the bound check, presumably
once everything settles out.  Does this simply suggest
the assignment should be in clocked process?  Is it fair
to assume the value will be clocked into a register eventually
and the combinatorial assignment shouldn't be used?  In other
words, does the bound assertion help enforce goodness?

Thanks for the additional information,
