class Prism::RescueNode
Представляет оператор rescue.
begin rescue Foo, *splat, Bar => ex foo ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ end
Foo, *splat, Bar находятся в поле exceptions. ex находится в поле reference.

end Реализует проверку равенства по типу для узла. По сути, это оператор ==, но без сравнения значений расположений. Проверяется только наличие расположений.
