Originally, the (.) form is there so you can say e.g (5 . mm) to get a
width of 5 mm.
Internally, the form is evalled by evalling the car and cdr and
multiplying them, so in effect, it can be used for more generic
multiplication (and division).
I do find it cleaner to add * (and /) as alternatives, but on the
other hand I wanted to keep this simple, and not add duplicate
functionality.
Also, I didn't want to give the impression that it is possible to
specify arbitrary lisp forms there.
