~/.config/youtube-dlg should just contain configuration files and not logs (which should go to $XDG_DATA_HOME/youtube-dlg/ ) nor youtube-dl binary (which should go to $XDG_CACHE_HOME).

Please also consider using appdirs instead of hardcoding ~/.config/

The L010 rule on capitalisation of keywords always errors with Inconsistent capitalisation of keywords. which can be misleading if the configuration isn't = consistent

I think giving different error messages based on the configuration ["consistent", "upper", "lower", "capitalise"] would be a lot more helpful.

This is probably a simple change that just requires a description being passe

If you serialize a big graph in a store that is off disk, we may run out of memory.

Either:

• Add a lru_cache (from py3 functools + this 2.7 implementation
• Depend on
