=== (other)

Source

# File lib/prism/node.rb, line 12524
def ===(other)
  other.is_a?(MatchLastLineNode) &&
    (flags === other.flags) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (content_loc.nil? == other.content_loc.nil?) &&
    (closing_loc.nil? == other.closing_loc.nil?) &&
    (unescaped === other.unescaped)
end

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