[IronPython] Implicit Cast to Float

[Dino Viehland]

Is there only one implicit conversion?  If so I think you should be able to call the op_Implicit method directly on XDate, e.g: XDate.op_Implicit(d).

If there's more than one I'm not sure how you'd select the one you want to call off the top of my head.

For the record - it *doesn't* implement IConvertible, so I can't use
that. I've searched the list and can find a very old discussion of
possible syntax - but no answer. :-(
