-  # `Parser` is the base class of all parser objects and contains
-  # a handful of helper methods that can allow for cleaner syntax.
-  #
-  # The generic type `T` represents the type of tokens a parser will
-  # operate on (usually `Char`).
-  # The generic type `V` represents the type of value that a parser
-  # will return when parsing is successful.
-  abstract class Parser(T, V)
-    # Accepts a `Tokens(T)` and either retuns a `Result(T, V)`, or raises a
-    # `ParserFail` exception with a message providing context of where
-    # in the chain the parsing failed.
-    #
-    # The `V` in the returned `Result` is arbitrary, but the `Tokens(T)` in
-    # the returned result MUST contain the parser's input, with some tokens
-    # removed from the front proprtional to what was parsed.
-    #
-    # Example:
-    # ```
-    # hello = ParsesHello.new # inherits from Parser(Char, String)
-    # input = Tokens.from_string("Hello world!")
-    #
-    # result = hello.parse(input)
-    # result.value  # => "Hello"
-    # result.tokens # => [' ', 'w', 'o', 'r', 'l', 'd', '!']
-    #
-    # bad_input = Tokens.from_string("Good evening world!")
-    # hello.parse(bad_input) # raises ParserFail
-    # ```
-    abstract def parse(tokens : Tokens(T)) : Result(T, V)
-
-    # Same as `#parse`, but returns `nil` instead of raising `ParserFail`.
