Hi Sven
I was using STON in P7 and Iâm now migrating to P10.
In the past I had no problem with a SortedCollection and now I have because of the block serialisation (of course). 
So I cannot really ignore or skip my sorted collection because it has what I want. 
I could go over all my collections and transform them into OrderedCollection for the saving. 
But may be there is a hook for that.
In fact I do not care to save the sortedCollection as soon as when I reload I restore it.

I read 

writeObject: anObject
	| instanceVariableNames |
	(instanceVariableNames := anObject class stonAllInstVarNames) isEmpty
		ifTrue: [ 
			self writeObject: anObject do: [ self encodeMap: #() ] ]
		ifFalse: [ 
			self writeObject: anObject streamMap: [ :dictionary | 
				instanceVariableNames do: [ :each | 
					(anObject instVarNamed: each)
						ifNotNil: [ :value | 
							dictionary at: each asSymbol put: value ]
						ifNil: [ 
							anObject stonShouldWriteNilInstVars 
								ifTrue: [ dictionary at: each asSymbol put: nil ] ] ] ] ]

It would be nice if we could say

MyClass >> transformedInstances
	{
	#series -> [:each | each asOrderedCollection ] .

	}

Or something like that. I was considering to hack my own version of STON to avoid to that in my model. 
Or serializing nicely SortedCollection.

May be I missed something obvious.
