Overlap? suggests, to me, that a subset of the things one range includes is the same as a subset of things that the other range includes. Within? suggests that all of one range is contained in a subset of the other range.

Exactly, but that's not how it's implemented in Facets ;)

I don't like #within? because it seems closer to #in? than to #include?.
a.within? b suggests the following:

  a  |-----| 
  b |-------|

I'd much rather have something else... #span?, perhaps?
