RescueNode.body returns the body of the begin...end block (marked A above). It has resbody_branches and branches to access the bodies of each rescue branch.

EnsureNode.body returns the body of the ensure branch (marked B above). It has currently no method to return the begin...end block, which may or may not be inside a rescue node.

I'd like to have an EnsureNode.body method that mirrors RescueNode.body (ie. returns the code before rescue/ensure), but the method name is already in use for something inconsistent.

1. Would it be okay to rename EnsureNode.body? I'd update rubocop/extensions to match once released.
2. If not, what could the method to return A be called on EnsureNode?
