question: What's the purpose of using a class variable?
This property is entirely scoped to the
.run
method, so it looks like it could be a local variable there?There was a problem hiding this comment.

Honestly didn't think it too much, I followed the pattern used for other options like
--no-color
, but thinking it now it definitely can be scoped just to.run
.I will change it later.
