Just a test repo for unused.

Running unused in the current repo currently prints the listing below. This mostly works great, but there are some gotchas re interfaces:

  • Implemented interfaces which are never used in, e.g., a return value is reported as Unused (UnusedInterface). This is not surprising.
  • An implemented interface method is reported as unused in the interface itself (UsedInterfaceMethodReturningInt). This is also not surprising, but may be a bigger problem than the first; maybe we should also look for implementations.
