Beyond the advice given here:

  https://isocpp.org/std/submit-a-proposal
  http://open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3370.html

1 It is often useful to survey existing implementations.
2 It is also useful to know which platforms should be considered to get to
a proposal with reasonable coverage.

Obviously the committee and community will add wider feedback beyond that
but a jump start could be helpful.

Closed source implementations obviously must be left to committee members
representing their particular
vendors and user-base but there may still be useful resources online.

Could we collect together a set of resources along those lines and add it
to isocpp.org and/or cppreference.com?

Starting with the obvious...

Which OS platforms do we need to consider 1st? - (thinking of something
like filesystem ts for example)
(recognising that all OS's should be supportable in principle)

  Posix:
    Linux
    BSD
  Windows
  what else?


Which compiler implementations:

  gcc
  clang
  what else is widely used and open source?


Which standard library implementations?

  gcc     libstdc++
  clang  cxx.llvm
  are the headers for VC++ collected online with the C++ redistributable?

What I was really hoping for was a list of urls pointing to browsable
and/or downloadable header files and documentation.

The more I look into this the trickier I am finding it to find
implementations that are both open source (even if the license is
proprietary) and widely used outside of gcc and clang.
This pool is far from wide enough to be considered a thorough survey of
existing implementations.

Several proprietary compilers have time limited trial versions. A few have
gone beyond this with "open source contributor editions" but you still have
to obtain licenses in some cases
and install them to get anywhere.

I wonder if a library of docker images (with the permission of the
proprietary implementation owners) might be a possible way forward?
