RE: [vhdl-200x] More operators for integers

Thanks YG,

The idea is not to replace the proposal for modular types - both proposals may indeed go forwards in one form or another...

Cheers,
Martin

I like that it is concise, simple, easy to understand, not fancy, with the "obvious caveats but we're warned".
This is probably the best route, the modular way is "safer"
but might not be as quick to implement in conforming tools, with more burden on the compliance tests as well...

I would prefer the modular implementation, for practical application, because dealing with widths different from 32 bits requires a number of explicit masks that are managed automatically by the modular type.

But if the modular type is not accepted, then the above proposal is the way to go IMHO.
