Well, if you do this, at some point you need to tell the extension
author to change the code.  Or they can just keep the code unchanged
forever.  I don't think it's worth the bother.

I would have liked to get a StaticAssert in the definition, but I don't
think it's possible.  A standard Assert() should be possible, though.
