FunctionalPlus is a small header-only library supporting you in reducing code noise and in dealing with only one single level of abstraction at a time. By increasing brevity and maintainability of your code it can improve productivity (and fun!) in the long run. It pursues these goals by providing pure and easy-to-use functions that free you from implementing commonly used flows of control over and over again.

For decades, the C and C++ standards treated multi-threading and concurrency as something existing outside the standard sphere - in that "target-dependent" world of shades which the "abstract machine" targeted by the standards doesn't cover. The immediate, cold-blooded replies of "C++ doesn't know what a thread is" in mountains of mailing list and newsgroup questions dealing with parallelism will forever serve as a reminder of this past.

Data-Oriented Design, or DOD for short, seeks to maximize efficiency by laying out data in such a way that their processing is as streamlined as possible. This is often against the usual object-based principles that naturally lead to grouping the information accordingly to the user-domain entities that it models. Consider for instance a game where large quantities of particles are rendered and moved around.

Return value optimization, simply RVO, is a compiler optimization technique that allows the compiler to construct the return value of a function at the call site.

The idea behind it is as follows: classes should not define any of the special functions (copy/move constructors/assignment, and the destructor) unless they are classes dedicated to resource management.
