I was trying to draw a contrast between the domains of i. and i:

Also, my use of !. (fit) was not meant to be ! (out of). I was talking
about potential language enhancements (which should focus on taking error
cases and re-using them for something that makes sense) and not about using
the language as it is now. Perhaps I should have used the chat forum, given
the subject matter?

Thanks,
