In which case, seems to me that coercion oerators should be considered to
return a reference, so as to be legal in lvalue situations.  Otherwise
you can't use coercion operators for true polymorphism.  Where is it defined
whether coercion operators return values or lvalues?  Is there anyway to
declare which you'd like?
