Admittedly this is a strict simplification to the code.

VS 2017 is fine either way.

You need to use a different constructor function, `refTuple()`, to opt into references. Otherwise, it's too easy to construct a tuple of references by mistake.

indexOfType<T, Tuple<...>>() searches the Tuple for a member of type T and returns its index. It fails to compile if there is not exactly one match.

TypeOfIndex<i, Tuple<...>> evaluates to the type of the Tuple member at the given index.

@kloepper pointed out a while back that every compiler you've ever heard of supports this. Plus, it's more concise, it's not prone to copy-paste errors, and it looks nicer.

At the time I wanted to remain consistent and I didn't feel like spending the time to update all my existing code. But, every time I've added a new header since I've cursed the include guard, so I finally broke down and changed it.

This prevents the compiler from reporting warnings in these headers while compiling application code. Hopefully this will stem the never-ending stream of complaints from people who enable pedantic warnings.

The license change is practically meaningless, as MIT and BSD 2-clause are legally equivalent. However, the BSD 2-clause license is sometimes confused for its ugly siblings, BSD 3-clause and BSD 4-clause. The MIT license is more immediately recognizeable for what it is.

Rémy Blank and Jason Choy (the two non-trivial contributors) are on record as approving this change:

Remove some function prototypes that apparently aren't needed and apparently tickle a bug in Clang trunk.
