It could take a std.aglorithm.openRight as its third, parameter, then you 
could choose to do one or the other. It just becomes a question of which is 
the default.

Certainly, my natural inclination is to go with having intervals be open on 
the right, but if you have a choice, it's less of an issue regardless of which 
is the default.
