Comfort, n. 
"We still have the spare tire? That's a comfort at least."
Cxxomfort (cxx as in C++, comfort as in comfort) is a small, header-only library that backports various facilities from more recent C++ Standards, providing access to them to previous versions such as C++03 or C++11: nullptr, begin/end, type_index, byte or the newer algorithms and functors, as well as many others, are made available.
Quick & Dirty Install

Install & Setup
|In the simplest form, installing the library is as simple as cloning the repo and adding the path to the compiler's #include search path.||
Usage is as simple as including a header and start coding:
#include <cxxomfort/backports.hpp> // for the backports #include <cxxomfort/cxxomfort.hpp> // for the whole package
The purpose of this library is to ease writing natural-feeling, forwards-compatible code once. As such, some design decisions are made that might conflict with conflict with certain pedantic "coding styles". For a quick, uncomprehensive check read Rationale, and also take a look at https://softwareengineering.stackexchange.com/questions/142836/achieving-forward-compatibility-with-c11 for evolution of the rationale.
The library does not aim to be perfect - that way lies madness, suffering, and suffering leads to anger, and anger leads to overused lines from movies. Instead, it aims to be "good enough" for the backports to be usable as far back as possible Standards-wise - all while remaining relatively simple.
For a list features included in this library and what are the Standard Proposals they come from check Implementation Status.
