immutable-data.ignoreNonConstDeclarations doesn't complain mutating function arguments #724
Description
Suggestion
So I think the idea of this rule is to treat everything immutable (by using const everywhere and avoiding typing everything as Readonly) and use let when explicitly want to mutate a variable/object. But it does not complain if mutating a function argument. Could it treat function arguments as if declared with const (and if you wish to mutate, use a naming pattern or something else)?
