Steps to reproduce

  1. define a prop with any name(Ex: value)
  2. input any code, to use the prop(Ex: value),console.log(value)
  3. before the prop use, input a function.It's param use prop's name(Ex: value),and function body insert an empty try-catch like demo.
  4. will show error value is not defined.

What is expected?

Step 2 's code will compile into console.log(__props.value)

What is actually happening?

In @vue/compiler-sfc's code

walkFunctionParams(node, registerLocalBinding)

and

when walk into function. And currentScope.value is not revert to true.cause this error!

In my opinion, this is a rather serious problem.
For example:
After the first use of props(value), and before the second use of it, if there is a function whose parameter is the name of this prop(value), then it will cause all subsequent properties to not function properly, leading to many issues.
