solidity的struct中包含了mapping，在使用中报内存初始化错误 

错误提示：struct contraining a (nested) mapping cannot be constructed

请教该怎么处理？

找了一下文档：https://docs.soliditylang.org/en/v0.7.1/070-breaking-changes.html#mappings-outside-storage
文档的意思是0.7版本后优化了这些不安全的写法，解决办法难道只有把mapping从struct中独立出来吗？？？

newProposal.proposer = msg.sender;
newProposal.eta = 0;
