--- Comment #3 from Thayne <astrotha...@gmail.com> ---
I don't think byGrapheme can be pure in general, because, in general, the input
range used doesn't necessarily have pure input methods. For example the input
range could read from I/O.
The solution would probably be to add pure if and only if the front, popFront,
and empty methods of the inputRange are themselves pure.
I'm not sure what the best way to do that would be.
