### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 17832
    def ===(other)
      other.is_a?(UntilNode) &&
        (flags === other.flags) &&
        (keyword_loc.nil? == other.keyword_loc.nil?) &&
        (do_keyword_loc.nil? == other.do_keyword_loc.nil?) &&
        (closing_loc.nil? == other.closing_loc.nil?) &&
        (predicate === other.predicate) &&

    end

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