Won't the user have to give their class a trait to use the function, if it
isn't a raw integer type?
The other concern is that the integer and string algorithms are different
in terms of
worst-case performance, as the string algorithm has to deal with
variable-length inputs.
Currently there is a spread_sort wrapper that selects integers or floats
using PTS,
and failing that, defaults to std::sort. I've yet to see a way to identify
that a data type is string-like.
I can remove the fallback if that's the desired behavior
(to avoid confusing the user about which algorithm is in use), but that
doesn't resolve the string issue.
