Hi
I’m spotting real inconsistency in the specification and use of newFrom:
In Pharo and Object we have
newFrom: aSimilarObject
"Create an object that has similar contents to aSimilarObject. If the
classes have any instance variables with the same names, copy them across. If
this is bad for a class, override this method."
^ (self isVariable
ifTrue: [self basicNew: aSimilarObject basicSize]
ifFalse: [self basicNew]) copySameFrom: aSimilarObject
The ANSI standard does not define newFrom:
Now in Pharo some classes such dictionary expect as argument a dictionary but
OrderedDictionary expects a like of association!
Set expects a collection,
Bag too and many others.
CompiledMethod expects a compiledMethod
I think that it would be good to strengthen this method and we could define
newFromSibling: but it looks like a copy to me.
