Is it possible to import a module from a user package that has the same name as a 'base' module?

iirc, this would require the PackageImports GHC language extension[1]:

OK, so that's a strike against the deprecation cycle, because people would need to use this extension in the transition period, or go for conditional compilation anyway.

I withdraw my objection to immediate removal.

Not if we just change the module names (note SafeSemaphore at the moment has different module names anyway). As a sidenote, the name SafeSemaphore is kind of silly if there's no dangerous semaphore...
