There are a handful of cases here that require renaming a module so it

doesn't overlap with a stdlib module name. There are also some cycles

here that we should still endeavor to fix, and some cycles will be

hidden by deduplication algorithm in the cycle detector, so fixing

these may expose other cycles.
