{-  There is a close correspondence between the pretty-printers in 'prettyCharacterSet'
    and the sub-parsers in 'Dhall.Parser.Expression.parsers'.  Most pretty-printers are
    named after the corresponding parser and the relationship between pretty-printers
    exactly matches the relationship between parsers.  This leads to the nice emergent
    property of automatically getting all the parentheses and precedences right.

    This approach has one major disadvantage: you can get an infinite loop if
    you add a new constructor to the syntax tree without adding a matching
    case the corresponding builder.
-}

{-| Pretty-print an 'Expr' using the given 'CharacterSet'.

'prettyCharacterSet' largely ignores 'Note's. 'Note's do however matter for
the layout of let-blocks:

>>> let inner = Let (Binding Nothing "x" Nothing Nothing Nothing (NaturalLit 1)) (Var (V "x" 0)) :: Expr Src ()
>>> prettyCharacterSet ASCII (Let (Binding Nothing "y" Nothing Nothing Nothing (NaturalLit 2)) inner)
let y = 2 let x = 1 in x
>>> prettyCharacterSet ASCII (Let (Binding Nothing "y" Nothing Nothing Nothing (NaturalLit 2)) (Note (Src unusedSourcePos unusedSourcePos "") inner))
let y = 2 in let x = 1 in x

This means the structure of parsed let-blocks is preserved.
