How I "guess" the class list.

I have for a while 
Object > othersClassList
othersClassList
|classList metodosSospechosos |
 classList := Set new.
metodosSospechosos := self  methodDict .
metodosSospechosos isEmpty
        ifFalse: [metodosSospechosos
                collect: [:cm | cm literals
                        select: [:any | any isVariableBinding]
                        thenCollect: [:each | (Smalltalk at: each key
ifAbsent:[])
                                ifNotNil: [  classList add: each key]]]].
                   
metodosSospechosos := self class methodDict .
metodosSospechosos isEmpty
        ifFalse: [metodosSospechosos
                collect: [:cm | cm literals
                        select: [:any | any isVariableBinding]
                        thenCollect: [:each | (Smalltalk at: each key
ifAbsent:[])
                                ifNotNil: [classList add: each key]]]].
                    classList remove: self name  ifAbsent: [].
                    ^classList

On a fresh Squeak3.9g-7054.image.

 GZipReadStream othersClassList gives me a Set(#FileStream #Smalltalk
#Sensor #MultiByteBinaryOrTextStream #Array #OrderedCollection #ByteArray
#SimpleServiceEntry #ZipWriteStream #FileModifyingSimpleServiceEntry
#FileList #FileDirectory)


The goal is kernel could load the "wished" normal class without change any
on Squeak3.9g-7054.image and as little as possible on kernel.

So the "exploration" consists in exchange info between kernel as you
provides plus my first Ladrillo.
That is fileOut Network-Kernel.st from Squeak3.9g-7054.image and fileIn in
kernel, loading RemoteCommand.st and doing SmalltalkImage current
saveAsNewVersion.

Now I have your kernel as provided and KernelSqueak3.9b-7053.1.image
It's time to build the next Ladrillo, what I wish was the minimal code what
lets understand gzip on kernel without complaints, Undefined or odd things.

I have the process semi automatic.
The rest of classes what I thing should go in second Ladrillo comes from
this semi-automatic process.
When complete , also I polish this process.
And if I could proper load ZipConstants on kernel , I could continue

In the end , looooog time, we have a kernel with minimal change as you have
now, several Ladrilllos and I hope a beautiful, safer house for all.

Cheers.

Edgar
