P1788/M0013.04 YES
I vote YES on Motion 13.04 -- seven standardized interval comparators.
This is a good compromise. Three may be theoretically sufficient, but
implementations are likely to provide more, and it would be a shame is
this resulted in a mess of similar but not identical operations.
An implementation may always provide additional functions not suggested
by the standard, but documentation must then clearly distinguish those
from the standard ones. Future motions might extend the set, but perhaps
only be recommending rather than requiring additional forms. In that sense
I see no conflict with the upcoming Motion 21 (Juergen's "overlap" functor).
Michel.
