    ^ Warning: codespell identified likely spelling errors. Any false positives? Add them to the list of ignored words in test/lint/lint-spelling.ignore-words.txt
  ```

  Note:
  * I ignore several valid alternative spellings ~, but changed homogenous
  to homogeneous as the latter is a more specific term according to the
  Google dictionary definitions I found~
  * homogenous is present in tinyformat, hence should be addressed upstream
  * process' is correct only if there are plural processes
