 This file expands on the existing `nat : parser ℕ` to provide parsers into any type `α` that
 can be represented by a numeral, which relies on `α` having a 0, 1, and addition operation.
 There are also convenience parsers that ensure that the numeral parsed in is not larger than

 As the parsing framework has completely changed in Lean 4
 there is no point porting these files directly.
 They can be rewritten from scratch as needed, just as for tactics.
