What's that regex trying to do? That would only match a slice consisting of nothing but spaces and `//`.

Are you trying to suggest only skipping lines that have been commented out using `//` at the beginning, but not anywhere else? That would just be `^\s*//`.

I question why we even need to worry about this. Why comment out a line with a `//~` error? If you need to disable the error check, delete the `~` character.
