Do you really consider a structure allowing anybody to change any byte
in its internal representation, eventually breaking its validity, as a
suitable candidate for a publicly used, standard, encoded string?
If the message is "Don't mess with my bytes, use my vendor high level
API to access me", we should not exspect C++ developpers to get it by
providing an hazardous backward compatible API.
I see the immutable string proposal as a way to express the definitely
needed breaking change in our string handling habits. A kind of shortcut
way, though, but quite a good one.
