Closure thisScript, thisPane and thisView in models

[marceltaeumel]

We use global bindings to provide access to the current script step, the pane, and the view:

{ 
   [:object | { #text -> 'Save'. #clicked -> [[ thisView saveAndClose ]] } ]
      -> { #view -> ButtonBar }. 
} asScript.

However, the user has to create a local binding when the exeuction time is deferred such as in this button-bar example:

{ 
   [:object | 
      | v |
      v := thisView.
      { #text -> 'Save'. #clicked -> [[ v saveAndClose ]] } ]
      -> { #view -> ButtonBar }. 
} asScript.

Maybe we can replace or shadow those global (dynamic) bindings during script interpretation.
