	return floating-point value

	return current string value (implicitly resets the token; useful only once)

constexpr position_t	get_position () const noexcept
	return position of last read token

std::string	get_token_string () const
	return the last read token (for errors only). Will never contain EOF (an arbitrary value that is not a valid char value, often -1), because 255 may legitimately occur. May contain NUL, which should be escaped.
