Figures that something like this would be posted on my day off. I put this through a parser that I cover, and found that the only failures were for top-level scalars, which we don't support, and for things we accept that we shouldn't. I'll look through the latter tomorrow, as well as the optional "i_" tests.

Test suites are a huge value add for a standard, so thank you, Nicolas, for researching and creating this one. I was surprised that JSON_checker failed some of the tests. I use its test suite too.
