C++11 implementations of standard components added in later C++ standards.

Function object wrappers for deferred calls or callbacks.

Open-methods are free-standing functions that work like virtual functions: they select the b​est overrider from a set, depending on the dynamic type of their arguments. This makes it possible to add polymorphic operations to existing classes, without modifying them. They make patterns like Visitor unnecessary.

A deterministic failure handling library partially simulating lightweight exceptions.

Boost.Parameter Library - Write functions that accept arguments by name.

Boost.Parameter Library Python bindings.

Extensible error reporting.
