Backporting string_view to older compilers

[woodb...@gmail.com]

I would like to encourage compiler developers to backport string_view to
older versions of their compilers. In particular, I'd like to see GCC, Clang
and MSVC do this.

String_view is one of the more useful elements of C++ 2017 imo.
Unfortunately, string_view wasn't introduced years ago. I hope compiler
vendors will take a "better late than never" attitude toward string_view
and make it available with their C++ 2011 and 2014 compilers.

Why not just use a newer version of the compiler? All of the three
mentioned by you are for free.

I can do that myself. This is for people who aren't able to use a
newer version of the compiler. If string_view had been part of C++
2011 or 2014, it would have been better.

Also, I would like to mention this again:

It has to do with adding a function like this:

virtual ::std::string_view what_view () const noexcept;

to std::exception. This didn't even make it into C++ 2017. :(

Brian has already been over this before:

I should beware entering into a discussion of the issue with him:
according to Brian, "... By attacking my reasoning you are attempting
to dissuade people from looking into my work". In other words, you may
be dragged into a debate on his company's commercial product, about
which I have neither any opinion nor any interest.

In this talk Titus Winters says they are going
to "pre-adopt" string_view into a library they're
developing:

(around the 49 minutes and 40 seconds mark)

This is further indication of the need for this
support for people using C++ 2011 compilers and I
hope compiler vendors will do the porting themselves.
