    # This method is to hook sequences of Tokens from the lexer and create a new hack-hook (unintended alliteration)
    # @example
    #    on_sequence RubyToken::TkNLINE, [RubyToken::TkSPACE], '*', RubyToken::TkNLINE do
    #      ... # TODO: Add in example code for this, I havn't decided on an API for Hackage::Sequence yet,
    #    end
    # The purpose of these sequences are to detect whether we have a matching possibility for a hack, which would determine
    # the necesity or lack there of to parse hooked objects in the hack type, the given example would be an implementation for
    # a hack that would allow the hooking of hacks that targeted specifically single line operations.
    #
    # WARNING: This API is subject to many changes as I examine the way that Hackage::Lexer deals with its Tokens and whether or not they are left as
