Hi Eliot --

Well, you wrote a test that does not account for the example I provided in my first e-mail. ;-) Maybe I used the wrong API. I combined #nextPut: with #nextArray. Looks reasonable to me.
The code in DataStreamTest looks scary: #testObject: #get: #put: #unStream: #streamedRepresentationOf: ... oh my ...
Best,
Marcel

My image freezes. It seems totally broken. That's why I asked. I wanted to learn more about the expected behavior. After that, I could write a test. ;-)
Interesting! The test worked second time for me (I used "instance first class = Color", which is false since in that case "instance first class = TransparentColor :-) ). That's 64 bits macOS.
Are you seeing this on 32-bit Windows? or...?
Best,
Marcel

Hi all --
Should the following work?
class := DoubleByteArray.
size := 10.
dummy := 123.
array := class new: size.
array atAllPut: dummy.
(DataStream newFileNamed: 'numbers')
nextPut: array;
close.
stream := DataStream fileNamed: 'numbers'.
load := stream readArray.
stream close.
load explore
Write a test :-)
testRawBits
((RawBitsArray subclasses reject: #isAbstract), ((RawBitsArray subclasses select: #isAbstract) collect: #subclasses)) flatten do:
[:class| | instance |
instance := class new: 10.
instance first isColor
ifTrue:
[1 to: instance size do: [:i| instance at: i put: (Color r: i * 1 g: i * 2 b: i * 3)]]
ifFalse:
[1 to: instance size do: [:i| instance at: i put: i]].
self assert: instance equals: (self testObject: instance) description: 'A ', class name, ' should be serializable']
see Tests-eem.494
