With all the new features C++14 and C++17 offer, it can be frustrating to be stuck with an old compiler that doesn't support them yet. Instead of forgoing structured bindings, fold expressions, and other additions, what if we could use them even on pre-2014 compilers?

Enter clang-from-the-future, a transpiler that reads C++17 programs and outputs standard C++11 source code. When used as a preprocessing step, it allows any compiler with C++11 support to compile a subset of C++14/17 programs. To enable this, CTFT rewrites new language features based on the program's abstract syntax tree and provides drop-in implementations for standard library additions.

In this talk, I will show how specifically this is achieved, how well it works in practice, and what's left to be done in the future.
