you could also add a CreateAnyNeg builder method that dispatches
to CreateFNeg/CreateNeg appropriately (and likewise for other
operations) to handle this kind of thing.  Not sure if this is
really a good idea, but it did strike me that other language
front-ends might find this helpful.

Ciao,

Duncan.
