Subject: [ruby-dev:49350] [Ruby trunk - Feature #11688] [Feedback] Struct and OpenStruct will be able to chain the Hash#dig Array#dig

Issue #11688 has been updated by Nobuyoshi Nakada.

Status changed from Open to Feedback

As those two classes were not parts of [Feature #11643], they are not rejected nor discussed.
`Struct#dig` should be at least, IMHO.

I feel that an argument of `OpenStruct#dig` should not raise an exception until it is used, as well as `Array` and `Hash`.

~~~ruby
[].dig("foo")          #=> no implicit conversion of String into Integer (TypeError)
[].dig(1, "foo")       #=> nil
OpenStruct.new.dig(0)  #=> undefined method `to_sym' for 0:Fixnum (NoMethodError)
~~~

It may be too strict though.
How do you think?
