I think there was definite merit in the host() function returning inet, as
you originally proposed (if only for consistency with the proposed changes
to network() and broadcast()).
A separate function for formatting output seems necessary, but if we don't
reach an agreement though, it ought to work to cast CIDR to INET to get
all four octets, no?

I think the typecast-to-text representation of CIDR should be visually the
same as the normal representation.
