  == No more automagic Python bytecompilation

  

  The current way of automatic *Python* byte-compiling of files outside Python-specific directories is too magical and error-prone.

  It is built on heuristics that are increasingly wrong.

- This change provides a way to opt out of it, and adjusts the guidelines to prefer explicit bytecompilation of such files. 

+ This change provides a way to opt out of it, and adjusts the guidelines to prefer explicit bytecompilation of such files.

  Later, the old behavior will either become opt-in only, or cease to exist.

  

  Note that bytecompilation in Python-specific directories (e.g. [filename]`/usr/lib/python3.6/`) is not affected.
