Actually, thinking further on this, I'm not sure I've ever actually been 
affected by the associativity of ?: one way or the other.

I have fallen foul of its precedence relative to concatenation, as in:

echo 'hello' . false ? ' world' : ' there' . '!';

But I think this is the same in other languages, and not related to this 
bug?
