Well, indeed they are both callable. But then one has to be careful to
be consistent, and everything ends up being functors.  I'll do a few
microbenchmarks to see what the cost implications of functors versus
functions would be, since measurement is better than opinion.

A short answer to your rhetorical question would be: the first is
primarily meant to be called, and the second is primarily intended for
indexing.
