I'd be in favor of that. Can't see it break stuff in anything but good ways.
I am not sure if it is that good.Say you want to make a generic vector class that accepts both integer and float values. This might seem trivial, well it is but it gets very ugly. You are going to need cast on each literal! Using C (non-generic) literal system in a generic language IMHO is very ugly even with the existence of implicit casting.
