My point was this statement can be written as both:

filter X by keeping the lines not matching pattern “regex"

and

filter X by discarding the lines matching pattern "regex"

So it would perhaps be a good idea to only allow `matching` rather than `not matching`

Hehe.. the `with expression` thing was me trying to come up with something that worked with `with | without | matching | not matching`… `where` is much better I agree.
