Ask the users to specify like Rust did,
or -- it's actually possible to compile
such code if the String protocol doesn't
operate char by value. std::string almost
does not do that. The more interesting
question is whether and how to design
existential containers that encapsulate
value semantics or provide a framework
to enable this possibility.
