carl 2020-07-25 22:09 administrator ~0003871	This just seems to be more trouble than it's worth; doing a few fixes suggests that the majority of the warnings are due to signed values hitting up against std::vector::size() or indices for vectors. The best you can do seems to be a bunch of `static_cast<size_t>` with `assert`s to check that values are `>0` first. Such asserts could be added (and `-Wsign-compare` is a useful way to find where they might be needed). Things might be neater with an extended / new `vector` type which use signed indices and `size().`
