Represents a rescue statement.
begin rescue Foo, *splat, Bar => ex foo ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ end
‘Foo, *splat, Bar` are in the `exceptions` field. `ex` is in the `reference` field.

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
