Hi Ivan You're free to do what you want in your own package, but... Having a Pretty class plus primitive printers int, bool is an advantage. For ints, bools, ... code tends to look neater if you use int or bool rather than pretty. Plus for ints and others you tend to need things like hex printers anyway, so one size via a type class doesn't fit all. As for the class - if I have a reasonably sized syntax tree I'd rather just do
pretty a
... than formulate a naming scheme like:
prettyExpr a
