This is the rest of the code:
ast := RBParser parseExpression: 'Object new. String new'.
ast annotateInClass: UndefinedObject.
(ast allChildren
select: [ :each | each isVariable and: [ each variableBinding
isLiteralBinding ] ])
collect: [ :each | each variableBinding binding value ]
-->
an OrderedCollection(Object String)
#variableBinding returns the object knowing all details about the
variables. It is only available after you annotated the AST with
#annotateInClass:.
