12 * The point of this class is to iterate through the Collapsed tree
13 * and add the property 'scopedName' to the tokens.
18 After spending some time looking at this, a few conclusions...
20 - this will have to be the base class of specific implementations.
21 - each implementation will have to decide how to declare a new scope
23 scopes are normally changed when these things occur:
26 globalScope(stmts) => statementsScope($global$, stmts)
30 objectScope(sname, props )
31 a = { .... } << scope is a $this$={a}
34 foo: function() {} $this$={object scope}
35 foo : ( xxx ? function() { } ? function() { ...} << conditional properties types
36 foo : (function() { return x })() << a property or function??? << depends on notes
37 foo : [ ] << a property.. do not drill down?
38 foo : xxxxx << a property..
42 functionScope(sname, stmts )
43 function a() { .... } << scope is a $this$={a}
44 a = function() { } << scope might be a $this$={a}
51 XX.yy(a,b, { .... }) << scope might be a or b.. $this$={a}
52 aa = XX.yy(a,b, { .... }) << scope might aa $this$={a}
54 callscope(name, pref, args)
