Those are not the only options.

Another possibility is to define a boost::any_string_view which is *not* 
a clone of {std,boost}::string_view but just does conversion duck-typing 
boilerplate (i.e. it defines no methods of its own other than 
conversions, and the only useful thing you can do with one is to assign 
it to a {std,boost,other}::string_view).

Ideally, this is what would appear in Boost.Core.

This is somewhat auto-hostile, but that's not unprecedented (Boost.Units 
is also auto-hostile).
