What should the contents of $judy be after assigning
$judy = new Person('Judy').'\n';
be in your opinion?
'Judy\n' ?
'Object\n' ?
'sprinkled icecream\n' ?
'3.14159265\n' ?
Imho implicit obj2str conversion is meaningless, and though I have abused
the construct myself a few times I am glad they corrected this behaviour.
Having to define your own stringifier forces you to think about and
implement what is logically the proper meaning of a conversion to an
otherwise incompatible type.
I am not sure how many scripts out in the field rely on such implicit
conversion but I do sympathize with you; it's frustrating at times to find
yet another changed property between point releases. But don't you agree
it's still better to have to change some code to something more correct
than to have to deal with all kinds of odd behaviour?
