I meant expression instead of statement, sorry, that's my fault. It's a
minor cosmetic change I should say, only to avoid long grouping of
expressions with an 'and' operator. It's better expressed as: let the
commas take the place of 'and' in assertion verifications... Maybe that
could be extended to other parts of the language, but the only place I
think it would be useful is in assertion statements.

Thanks,
Fabio
