Same semantics does not cover U++ moveable. Now I agree it is unlikely, but so I thought about std::string until I met implementation that is not U++ moveable...

I looked into std::basic_string in this post, message #59178.

Quote:

Story of std::basic_string (GLIBCXX implementation)

It's surprising that a basic_string<ch> would cause trouble (core dump etc) when treated as raw bytes. Digging into its implementation (in <bits/basic_string.h>), we have the data members
...

.

On the same post, I proposed to use class traits to handle Moveable. There are details I could not iron out. Also, it might not be compatible with very old c++ because I have an added goal to allow non-trivially relocatable class objects, which can be corrected pre- or post relocation, be housed in std::vector or upp::Vector.
