* JSDoc:positional matching of destructured params
1. When looking up tags for a parameter whose name is a binding pattern, use
the index of the parameter to get the type.
2. When reporting errors for `@param` tags with no matching parameter
name, do not report the error for tags whose index in the `@param` tag list
matches the index of a parameter whose name is a binding pattern.
