Please don't lecture others. I hate top posting. I'm 54 and hated the
rising popularity of programs like Outlook which encouraged top posting.
Gmail makes top posting the default. So unless I'm responding to more than

We lost the battle of top versus bottom posting twenty years ago. Move on.

No, I mean ambiguous in the sense that a naive reader of the script might
wonder what the author intended. Really, there's no good reason to save a
couple of characters in this situation. Be explicit about what you intend
to avoid confusion.
