Is that actually true, or would handling exceptions within the 
constructor allow one to initialise the object to an invalid 
state and thus still follow RAII paradigms correctly?

The amount of bugs and pain I've had to deal with in production 
code because of throwing constructors makes me lean more towards 
Walter's viewpoint here. Even one of our most basic datatypes - 
the IEEE float - initialises to an invalid state. Why can't RAII 
objects do the same if it performs operations it *knows* throw 
exceptions?
