yes sorry i meant global variables , the ones you define in workspace like a := 1.�
Those aren�t globals. Everything you do in the workspace is compiled as method (UndefinedObect>>#DoIt) and executed. There are only a handful of global values and there is the smalltalk dictionary where names can be looked up.
They live in the �bindings� ivar of Workspace.
When you compile code with the �requestor� not nil, it will put a�OCRequestorScope into the scope chain.
This means that when Opal Semantic analysis asks the scope for the definition of a name, it will call
#lookupVar: on that scope, which is then doing:
(requestor bindingOf: name asSymbol) ifNotNil: [:assoc |�
^ OCLiteralVariable new assoc: assoc; scope: self; yourself].
^ super lookupVar: name.
Which means that variables in the Workspace are compiled as literal variables (like globals),
but the binding comes from a dictionary that is in the ivar �bindings� of the Workspace.
