I did understand that it is a zero-width overlay, so the
description wasn't confusing to me.

For non-zero width overlays, it is quite easy to have
point to each side of the overlay's "border": it depends
on which side you are coming from. For me, at least, it
is intuitive.

Quite possibly I'm not understanding what you are trying
to achieve. The mental model I got from your description
is that the overlay describes some property of the arg
value in question (the name given to the corresponding
formal argument elsewhere in the function declaration
viz. definition). That's why I'd expect the overlay to
cover /all/ of the arg value (and let it grow and shrink
automatically as the latter is edited by the user).

But, as said, perhaps I'm lost in the woods.If yes, then
sorry for that :)

Cheers
