What might be a little easier, is to add a "little"
static analysis to the decorators.  At that point
a "warning" message could be supplied.

But this could get ugly, at this point I don't
know if this would generate many superfluous
warnings (like many of the existing FPGA tools).

Another common error (and sometimes hard to debug)
is when folks mix `bool` and `intbv()[1:]`.
