Continuing the discussion from Easier handling of context variables:
Well, in this case the discussion here in Discourse existed prior to the pull request. As such, I think continuing it here makes sense, unless it’s about specific lines of code… which are better commented on on GitHub.
I’d suggest to handle it like this: If a discussion here is connected to a PR, link to the discussion here from the PR by adding a comment there. If a broader discussion comes up from a PR, that can be moved here, then apply the same rule in reverse.
What do you think?
