Does the sequence extension support exceptions, or ignores?

[daobrien]

Use case:
We prefer to flag "check" as a verb and recommend an alternative, but we want to allow "check out", referring to "checking out a branch" or similar.

We currently use the sequence extension, as follows:

tokens:
    - tag: VB
      pattern: check

Can I refactor this to allow/ignore "check out"?
Perhaps something like "check not followed by out"? I'm not sure what regexes, if any, I can use in these patterns.

Thanks

This appears to be working, but need to test more thoroughly:

tokens:
    - tag: VB
      pattern: check(?! out)

Happy to see improvements or suggestions.

Thanks

This allows "check out the repo" but it also allows "check out the docs" which is obviously no good.
