I just stumbled on that when replying to your other email about odd 
results when reading from nvidia struct.

IMHO to make this code more reliable you need to attach more info to the 
layouts of your structs, so that for each field you know what CrossPoint 
type you wanna create.

If you have some enum with all the types you support - then you can just 
attach enum constants to struct field layouts - and then you can recover 
that layout attribute from the logic in BasicNativeStruct, and make sure 
that the right wrapping abstraction is created.
