Gilles commented on MATH-754:
-----------------------------
What's the problem with a class? That's usually how you solve this kind of
problem in OO programming: Instances of this class will be returned by a
constructor that will make sure that the requirement is satisfied, and, as
"Fraction" objects, they will be used transparently by any method that expects
an argument of type "Fraction".

> I'm writing some code which outputs fractional measurements meant for human
> consumption. I need a constructor for Fraction which allows you to restrict
> the denominators to a finite set. This is necessary due to the fact that
> real-world tools are only available with certain fractions. For example, it's
> next to impossible to find a ruler with 1/7 inch marked :).
> I'm attaching a patch which implements the functionality. I've attempted to
> mimic the style of the existing code as much as possible. One caveat: I don't
> speak French so the french error message is a computer-generated translation
> and probably very poor.
