I agree with that.  I consider the difficulty of adding a reliable
immutable attribute in most languages to be a serious piece of
misdesign, but there isn't a huge amount of point unless it is done
properly.  Unreliable safety devices are as likely to increase
errors as reduce them, at least in the hands of the naive.
