- Refactored functions - Several functions are inlined and removed from global namespace - Moved function from `packages.el` to `func.el` - Replaced `(when (not foo) bar)` with `(unless foo bar)` - Replaced unnecessary backquote construct with simple quotation - Replaced `pcase` form with only one-arm with `when` or `unless` form
