Answer
Creating cyclic dependencies and ignoring performance impacts.
A common mistake is introducing cyclic dependencies between decorators, which can lead to infinite loops. Additionally, excessive decoration can degrade performance due to increased method call overhead. It's crucial to design with performance in mind and ensure decorators are applied logically and efficiently. For example, ensure that decorators are necessary and don't duplicate roles or responsibilities in your e-commerce application.
