I was imagining something more lightweight, like a union...

There's also the possibility of simply defining implicit conversions 
between the two styles.

But a better solution would be to decide from the outset that one style 
is "right" and the other is "wrong", so only one needs to be supported 
and no conversions are needed.  (I mean that partly tongue-in-cheek.)
