-  # `Map` is a `Parser` that tries to parse using another parser,
-  # and then changing the result of that parser to a different value.
-  #
-  # Example:
-  # ```
-  # # Where `Digits` is some parser that returns an array of digit characters
-  # parse_i32 = Digits.new.map { |x| x.join.to_i32 }
-  # result = parse_i32.parse(Tokens.from_string("1234"))
-  # result.value # => 1234 (Int32)
-  # ```
-  class Map(T, V, U) < Parser(T, U)
-    # Accepts the parser to use and the function to apply to the result.
-    def initialize(@p : Parser(T, V), &block : V -> U)
-      @f = block
-    end
-
-    # Tries to parse with the given parser and applies the
-    # function to the result if successful.
-    def parse(tokens : Tokens(T)) : Result(T, U)
-      result = @p.parse(tokens)
-      Result.new(result.tokens, @f.call(result.value))
-    rescue ex : ParserFail
-      raise ParserFail.new("Map: #{ex.message}")
