GPPlot is something that you add to a GNUPlot instance. I guess we have

How do you define the semantic?
Namespace current: GNUPlot [
Object subclass: GNUPlot [
Foo := nil.
foo [
^GNUPlot.Foo
]
bla [
^Foo
]
]
Object subclass: SomethingPlog [
foo [
^GNUPlot.Foo
]
]
Object subclass: Foo [
]
]
>>#bla and >>#foo the bytecode appears to be:
[3] source code line number 2
push Global Variable #Foo->nil
[5] return stack top
Which means foo is resolved at runtime that one can never access
a class variable?

Hi,
if we accept that the class name *cannot* be the same as the namespace
name hence the code becomes:
Namespace current: GNUPlot [
Gplot >> foo [
^GNUPlot.Foo
]
]
The compiler will create a DeferedVariableBinding and when Foo class is
created it replaces the DeferedVariableBinding with a VariableBinding.
