The fact remains that those who have used the existing functionality as 
it is implemented and documented will, of this change isn't reverted, 
have to make a gratuitous change to their currently working programs.

I'm not really too concerned with whether the behavior is "erroneous" - 
that is indeed in the realm of value judgment. I'm concerned about the 
impression the user community will get as they see such changes made to 
the language with no more apparent justification than the whim of an 
individual developer.

Because some immoderate language has been used in this thread I would 
like to underline that these remarks are not directed personally at 
Martin, for whom I have the utmost respect as a developer, but at the 
lack of process that allows circumstances like this to arise.
