Microsoft released a new compiler for VC++ that complies with more of modern C++ than the standard compiler.

https://blogs.msdn.microsoft.com/vcblog/2016/03/31/clang-with-microsoft-codegen-march-2016-released/

Is it possible to support it by creating a new script based on  Lib/distutils/msvccompiler.py to Lib/distutils and adding a new item in the following dictionary in Lib/distutils/ccompiler.py?  


compiler_class = { 'unix':    ('unixccompiler', 'UnixCCompiler',
                               "standard UNIX-style compiler"),
                   'msvc':    ('_msvccompiler', 'MSVCCompiler',
                               "Microsoft Visual C++"),
                   'cygwin':  ('cygwinccompiler', 'CygwinCCompiler',
                               "Cygwin port of GNU C Compiler for Win32"),
                   'mingw32': ('cygwinccompiler', 'Mingw32CCompiler',
                               "Mingw32 port of GNU C Compiler for Win32"),
                   'bcpp':    ('bcppcompiler', 'BCPPCompiler',
                               "Borland C++ Compiler"),
                 }

The executable of it is at C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\ClangC2\bin\amd64.  The help message of it is:
