Free functions at namespace scope. The analogy would be module-level
functions in Python. C++ also has multiple string types, but the
availability of overloading makes this approach practical (is it time for
Python multimethods yet?)
If I were to make arguments against string member functions in Python I'd
be talking about the degree of coupling between algorithms and data
structures, how it interferes with genericity, and the difficulty that
users will have in making "string-like" types...
