Subset of the old Clang Plugin needles

Most needles from current clang plugin minus some of the inheritance needles.
So…let's talk about fixtures. I have learned, though much pain, that big, shared fixtures are a great way to tightly couple all your tests together such that you're afraid to ever change any of your fixture data again, lest you cause tests to become invalid—that is to keep passing but no longer be testing what they're supposed to test.

I don't really think that's what you're doing here, however. It looks like you're just using FIXTURE as a big bucket of things you later compare against. What's more, it doesn't look like you compare against any one key more than once. So why bundle it all together here, lexically far from what the test that's using it?
