[ruby-core:119639] Re: Behavior of raising from rescue blocks when multiple rescue blocks exist

From: Austin Ziegler via ruby-core <ruby-core@...>
Date: 2024-10-29 18:07:08 UTC
List: ruby-core #119639
RuntimeError is a descendant of StandardError, and rescues happen exactly
once per exception handling block.

That is, your first code example will never hit RuntimeError because it's
swallowed by the implicit StandardError.

Here's a class tree of Exception from my local irb:
