Instance Attribute Details

#arguments ⇒ Object (readonly)

The arguments to the break statement, if present. These can be any [non-void expressions](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

end

Instance Method Details

#===(other) ⇒ Object

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