mostly asking cause i saw this article and it stirred my interest and it seems like it'd be much easier to find "valid" but buggy inputs in a build tool vs a compiler https://news.ycombinator.com/item?id=17387954 i might screw around with afl (the fuzzer described in the article) later -- not quite sure what i'd focus on but even just generating valid (and invalid!) testprojects seems like it could be useful for e.g. perf testing, even if pants is 100% bug-free (i know my code is 100% bug-free obviously)
