indeed you can't, and if I recall correctly I wrote it somewhere. The point is eventually 
if such distinction is worth considering or if, instead, the two cases should be handled
as degenerate (equivalent) notations. 

IMHO, they should be kept distinct, and this disqualifies that implementation strategy.
Too much magic would happen otherwise.
