Sorry, for all these "ping"-style messages, but this wasn't resolved.
It's redundant and obsolete since full complex number support has been
introduced, isn't it?
OK, perhaps cmod() will be hidden at some time in the future. To be on
the safe side, I think a good advice (for the few people who actually
have been using cmod) is to use abs() always.
