### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 6730
    def ===(other)
      other.is_a?(EnsureNode) &&
        (ensure_keyword_loc.nil? == other.ensure_keyword_loc.nil?) &&
        (statements === other.statements) &&
        (end_keyword_loc.nil? == other.end_keyword_loc.nil?)
    end

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