I'm not sold on this. I certainly see how it would be useful, given
the "falsy" nature of 0 and false and all that, but:
* There isn't a compelling enough use case *outside the framework*
that would warrant putting this function in the dollar namespace. And
without a short name it wouldn't save you much typing.
* Using a ternary requires a bit more typing, but I think it produces
more readable code. The purpose of $D would not be immediately
apparent to people who don't work with the internals of Prototype
every day.
Cheers,
Andrew
