Re: [myhdl-list] intbv with max != 2**n. Error or annoyance?

[Per K. <bas...@gm...>]

Hm, that would enforce a coding style where every combinatorial cloud must
be written monolithically. You could never break down a combinatorial
problem into parts.

I think this is a bad coding style. It makes for unreadable code, and it
limits the amount of complexity that can be tackled successfully.
