      No, once a variable is bound with a value, that value cannot be changed
      within the scope of the variable.

      If you re-open the scope you can assign a new value to the variable for the
      new scope. This is done in a recursive call, or in the context of the
      processing of another source tree node.

      I hope this helps.
