any_function.h is a single header public domain utility library for C++11.

It is intended to serve as a functional counterpart to the std::any, by providing a single, concrete class any_function which can receive almost any callable object, from function pointers to lambdas to instantiations of std::function.

This library is still under development and its API and implementation details are subject to change.

TODO

• Retain reference/const/volatile qualification in parameter and return type metadata
• L-value reference parameters (should work, but needs testing)
• R-value reference parameters
• L-value reference return types
• R-value reference return types
• Const/volatile qualified parameters
• Const/volatile qualified return type
• Mutable lambdas / stateful function objects
