In my opinion, the "east-const" vs "west-const" debate is just the tip of the iceberg. It is a sign that we would need additional "spelling conventions" as far as the types are concerned. Those rules might not be required for a successful compilation, but they should exist nonetheless.
In written english, the spelling rules say for example that each comma (",") should be followed by exactly one space (etc.), as well as each question mark ("?"), etc.
it is still possible to Write a sentence ,and to ignore totally those rules ;but it is considered Ugly -and rightfuly so - !
