This PR adds the option `pp.parens` (default: false) that causes the pretty printer to eagerly insert parentheses, which can be useful for teaching and for understanding the structure of expressions. For example, it causes `p → q → r` to pretty print as `p → (q → r)`. Any notations with precedence greater than or equal to `maxPrec` do not receive such discretionary parentheses, since this precedence level is considered to be infinity. This option was a feature in the Lean 3 community edition. |
