+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.
