How about generalizing even further: instead of specifying the end of
range by an iterator, allow an arbitrary function that takes an iterator
as argument.  For example, in processing an array of characters, you could
then specify the end of the range either by a pointer, by a test for *it
== '\0', or by a function that returns true the first n-1 times it is
called and returns false the n-th time (to specify a range of length n).
