iron-utility is a collection of (potentially) useful type-oriented utilities for C++ as a header-only library, most applicable to SFINAE/enable_if template metaprogramming.
Download utility.h to your project's source tree, include with #include "path/to/utility.h" and go!
Requires a roughly-compliant C++14 compiler and STL, as std::enable_if_t support is required (but this can be easily worked around). Visual Studio 2015's MSVC++ compiler works fine and passes all tests. The version of Clang included with Xcode 7.3 is known to work (with the -std=c++14 flag specified), as well as the Clang 3.8 release. GCC 5.x is good to go also.
Work-in-progress documentation is available at https://boatilus.gitbooks.io/iron-utility/content, generated from Markdown files within this repository's docs directory.
