cling building on windows nov2017
With visual studio 2015 begin with upgrading to update3 since there's warnings about lower versions in the build scripts.
Also make sure python is in the path (tried with python2)
Building win32 won't work, neither CL toolset nor final binary will work. Stick to x64

Cheney on the MTA in C++11
// Syntax demo for writing Cheney on the MTA style code in C++11
// (see http://home.pipeline.com/~hbaker1/CheneyMTA.html for more info)
//
// Using variadic macros, I managed to design a syntax that is good enough
// to write in, as opposed to the automated code generation that COTMTA
// originally envisioned.
//
// key reasons why I intend to use this:
// * Writing a Scheme interpreter that keeps the C stack compact
