    Parses, and lazily rewrites Destructuring Assignment expressions. The rewriting strategy involves inserting a placeholder RewritableAssignmentExpression into the AST, whose content expression can be completely rewritten at a later time.
    
    Lazy rewriting ensures that errors do not occur due to eagerly rewriting nodes which form part of a binding pattern, thus breaking the meaning of the pattern --- or by eagerly rewriting ambiguous constructs that are not immediately known
