So?

The right way to handle this is for those methods to be templated, in
which case a) the code only needs to be written O(1) times, not O(N)
times, and b) users can potentially specialize for their own string
types as well.

If done cleverly, even the (pointer, size) variants should be able to
wrap the arguments in a View, such that those method definitions are
trivial.
