I agree it's a very odd error report,
I 'd just like to add that you could protect your hairiness level
contributing to the factory default defaults service, there you can define
factory defaults to symbols which in some cases saves you from crashing in
that way.
Of course there 're some situations a default value is not an option so I
'm happy Howard also agrees to change the error reporting in these cases...
but anyway that's my two cents. (by the way it would be great to have a
default value for hairiness set to false!)
