If the arraysize > 0 bit is really important, put a COMPILE_ASSERT here so that
it holds even after you fix this TODO.

This is get around a compiler error from ArraySizeHelper so I don't think that's
necessary.

I wouldn't do this comment since the file is small enough for it to be easy to
understand. For complex cases where a divider really helps, most code generally
uses hyphens.

[Robert Sesek, 2013/01/15 21:40:50]

Done.
