In this answer How to test if a string is a vim command?
After there is a comment asking motivation of the question. I added an answer to specify that point, with concrete code, key mapping, examples of workflow.
But it was deleted, under the reason of
answers should only be used for answers.
Thus I wonder, is that fair? Or should I just silently shut up.
P.S. I asked the question, accecpt an eariler answer. Then answered the comment's query, instead of edit the question per se, because it would be too lengthy for the body of question itself, in the hope of just to help.
