=== (other)

Source

# File lib/prism/node.rb, line 7082
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.
