printf don't always perform IO : if you ask it for a String it will
happily turn into sprintf for you, if you use it in the IO Monad, it
will indeed perform IO, but there's nothing fundamentally IO bound in
printf logic.
That's even *more* impossible... o_O
Why ?
How can one function have more than one type signature?
