Any thoughts on scoring vis-a-vis TIO's auto-complete feature? Say I write :s/old/new
on TIO. This works, and I could count it as 10 bytes. But if I were using actual Vim, I'd have to hit Enter before the substitution did anything (and I don't recall whether the final slash would be needed too)--so should it be 11 (or 12) bytes?
On the one hand, the implementation defines the language, so TIO Vim could be considered its own dialect; on the other hand, the TIO interpreter is actually V, not Vim, so the auto-completion is arguably a feature of V that shouldn't be used in pure Vim answers.
