       The AtteanX::API::Lexer role provides a common interface and implementation for lexer implementations,
       allowing line-based buffer filling, and consuming of characters, constant strings, and fixed-length
       buffers.

       "fill_buffer"
           Fills the buffer with a new line from the underlying filehandle.

       "check_for_bom"
           Remove a BOM character if one appears at the start of the buffer.

       get_char_safe( $char )
           Consume  the  single character $char from the buffer.  Throw an error if $char is not at the start of
           the buffer.

       get_char( $char )
           Consume and return a single character from the buffer.

       peek_char( $char )
           Return a single character from the start of the buffer.

       read_word( $word )
           Consume the string $word from the start of the buffer.  Throw an error if $word is not at  the  start
           of the buffer.

       read_length( $length )
           Consume and return $length characters  from the start of the buffer.
