A lot of functions in Phobos are templated on string type, so you don't have to
define multiple versions of them. Very few, if any, are actually defined for
multiple string types. Now, because each template instantiation results in
another version of the function in the resulting binary, if you try and use all
of the functions with all of the string types, then you do get combinatorial
problems. But thanks to the templates, you don't have to worry about it
directly, and it's not like it's going to be a typical use case for most string
functions to be used by multiple string types in the same program. It will
happen, but not enough to generally be an issue.
