While I'm only +0 for a standard odict I'm wondering that discussing
this topic leads to the auctoritative conclusion that it is unsolvable,
we have to accept infinite diversity etc. where people like me seeing a
classification immediately ( mathematical education? ) . Of course this
matter is trivial but we already know about monster-threads revolving
around decorator syntax ( including hurt souls and semi-scientific
papers ) and abandoning the print statement in Python 3.0.
