* Eliminate well-known symbols in the checker: 2021 edition * Actually update the lib text to say unique symbol, too (this is unneeded with compat code in place, but this makes goto-def make more sense) * Add test showing mismatched symbol constructor type interop * Add more test cases for some other related issues this fixes * Revert computed name change * Style comments
