<pre>In _collect_matching_tests, a lot of membership tests are done on a giant list of strings. By making it a set instead, we can make those much faster, and there's no reason for it to be a list.
With ~45k tests and some 1000 expectations, this reduces the parse time from 34s to 3s on my machine.</pre>
