Comment space is very short.
Sometimes I have a very long comment where I would like to have the same capabilities as are available for Answers (e.g., paste long lists, show code, figures, ...) in order for my comment to be understood.
I haven't done this yet but I could write the Comment as an Answer with the first line:
"This is not an Answer but too long for a Comment"
Is it permissable to write a Comment as an Answer?
