No overhead is good, but there might be a different way to achieve it:

   split( tokens, make_iterator_range(input), ... );

We could even get away with changing split(), but letting
make_iterator_range() return a const iterator_range<T> (Erics
suggestion). But OTOT, that would disallow a call to mutable functions
afterwards. We could also add make_const_iterator_range().

Anyway, I do think the current behavior can be suprising at first and
that those who want efficiency should do the extra work (at least in C++03).
