Is the naming infelicitous? Yes, no argument from me here.

But: I'd guess that Strideable, being a protocol for numeric types, comes
into the picture mostly when implementing generic numeric algorithms, and
its associated Stride type (if I remember correctly from reading code
comments) should really be Distance but for current limitations in the
language. I have no doubt that someone who knows the insides of Strideable
to that level of detail has the expertise and imagination to conjure up a
meaning for `stride(of: Int)` other than the stride size in bytes of
consecutive Ints, but I venture that it'd still take some effort and
wouldn't be an unintentional misunderstanding :P
