"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.
