        provides and registers a fresh variable in the current scope. It takes parent scopes into account and only reuses names of synthetic variables from parent scopes. Pseudo scopes are treated as if they were part of their parent scope.
        Parameters:
        withUniqueName - This is a workaround for https://bugs.eclipse.org/bugs/show_bug.cgi?id=445949
