I've been writing ring buffers wrong all these years

That only works for compile time constants, though. With a power of two sized buffer you can just store the mask and decide how large you want your buffer to be at runtime.

libdivide (http://libdivide.com) implements similar logic at runtime

You can also compute the optimization at runtime, same as the compiler does. Libtheora contains code for this, used for quantizing video data.
