BooK, we are not talking topology here even if we are free to borrow syntax from anywhere for notational convenience and mnemonic value. But here, this will buy us not much, will confuse editors like vi or emacs; Also the notation itself is not even universally adopted. In French schools, we were writing [1..10[ for the [1..10). I find the French notation more mnemonic because it shows clearly that the right bracket is "porous". -- stef > > (Sorry for the late post, but p6l is always 200 messages ahead of me) > > -- > Philippe "BooK" Bruhat > > One lesson learned is never enough. > (Moral from Groo The Wanderer #104 (Epic)) > >
