Single stepping through debugger can observe an anOrderedCollection
object in an inconsistent state after creation but before
initialisation. This threw an error when the inspector asked for the
size of the object - now handled.<br>

I understand, OrderedCollection new inspect won't fail.<br>
But you can't debugIt step by step, because just after basicNew, it
will be uninitialized.<br>

Thats right, I could not debug past the basicNew and through the
'setCollection:' initialization, but I expect to be able to. I was
debugging some code step-by-step, which happened to create a new
OrderCollection, which caused the debugger to produce a
DoesNotUnderstand error that I could not get past. This can be
simulated by... 'self halt. OrderedCollection new: 5.'<br>

What now is the status of my two Inbox submissions? I assume they are
rejected but it doesn't specifically say so. <br>
Do you correct them as necessary to push them forward? Or do I resubmit
new ones taking on board the feedback from yourself and Levente?<br>

Is it a good idea to catch all Exception ?<br>
Otherwise, there is no reason to invoke size twice, it just could be<br>
^ [ object size ] on: Error do: [ 0 ]</div>
