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.
