Use smartmatch instead of regex here
Tidying up
`if (none { ... } ...)` looks better than `unless (any { ... } ...)`
Use the never version of `List::Util`, as it now has such functions as `any`, `none`, `notall`
Use `List::Util` instead of `List::MoreUtils`
and turn `unless any` into `if none`
Use `qw` with parentheses: `qw( ... )` instead of `qw[ ... ]`
Don't use `qw` if there's only one thing to import
Delete unused code
Minor changes.
