Lines 15 to 17 in bd2509b

	pub struct Function {
	pub params: Vec<Param>,

I need to update the type of params from Vec<Param> to Vec<ParamOrTsParamProp>, which will cause a significant amount of changes.

In fact, the introduction of deferred has led to ParamOrTsParamProp appearing more frequently in the TypeScript source code than Param. This nested structure will bring cumbersome matching to the visitor.

Perhaps we have another option, to merge the structures of TsParamProp and Param into one. What do you think? @kdy1

Merging the two types sounds good to me

I have observed that Babel also distinctly differentiates between TSParameterProperty and Pattern.
It might be necessary to communicate with Babel to explore better implementation methods.
