-"""Temporary old _low-like layer.
-
-Eases refactoring burden while we overhaul the Python framework.
-
-Plan:
- The layers used to look like:
- ... # outside _adapter
- fore.py + rear.py # visible outside _adapter
- _low
- _c
- The layers currently look like:
- ... # outside _adapter
- fore.py + rear.py # visible outside _adapter
- _low_intermediary # adapter for new '_low' to old '_low'
- _low # new '_low'
- _c # new '_c'
- We will later remove _low_intermediary after refactoring of fore.py and
- rear.py according to the ticket system refactoring and get:
- ... # outside _adapter, refactored
- fore.py + rear.py # visible outside _adapter, refactored
- _low # new '_low'
- _c # new '_c'
