What Mohammed was proposing was a simple fallback mechanism for the case
when the option is not bound. Personally, I like it more than the
$NAME-bound magic: suppose you have an option named "upper-bound", you
will then have to refer to something like "upper-bound-bound" etc. Also,
what would be the advantage of this compared to the p:bound() function
you proposed earlier?
