Curious that they were in the list just now. I was playing with them last 
night with some problems;)

Question: what was the last version of Squeak the package on SM was known 
to work with?

My problems. I use MathMorphs.pdf from the Squeak book as my tutorial. 
Assigning a name as in
"punto := self" did nothing.
I build a silly little class called Person with one instance variable 
'name'. I expected "Person new name: 'Frits' ; self" to give me a wrapper 
on an instance of a Person. Instead I got a Morph Explorer. I do get the 
correct result on a point.

I am exploring the statement that MorphWrappers are Squeak's answer to 
Naked Objects.
