Note: the 'Tags' column refers to code features that may be found in the code.
      A few examples are presented below.

- REM_RECURSION: the code contains recursive calls, but they were removed or
  commented in the current Eva test cases.
- UNUSED_RECURSION: the code contains recursive calls (either in the main
  application/library, or in test cases), but the current Eva targets do
  not call them.
