Description

The regression was introduced by https://bugs.ruby-lang.org/issues/16127

In short on 2.6 SimpleDelegator would always call respond_to? on the delegated object to figure if it should delegate or error.

But on 2.7 it doesn't do so if the delegated object is a BasicObject, which broke some of our code.

The fix was merged on master by jeremyevans0 (Jeremy Evans) as f2552216d43040cd42bbb9fd484eab6c70856fe6 (https://github.com/ruby/ruby/pull/2875).

However I'd like to require a backport to the ruby_2_7 branch.
