And as long as the use of the template doesn't cause the C++ compiler
to do anything unexpected.

Less dangerous than just casting types, since at least you're using
the C++ type system rather than abusing it. However, what I had in
mind was to dispense with the IDL generated Complex struct altogether
and modify the call descriptors, object references and skeleton
classes to use the STL complex type directly.
Regardless, like I said before, I don't think you should be thinking
about any of this unless you find doing the easy translation function
is too slow.
Cheers,
Duncan.
