Similar to type, this method returns a symbol that you can use for splitting on the type of the node without having to do a long === chain. Note that like type, it will still be slower than using == for a single class, but should be faster in a case statement or an array comparison.

def ===(other)
other.is_a?(CallOrWriteNode) &&
(flags === other.flags) &&
(receiver === other.receiver) &&
(call_operator_loc.nil? == other.call_operator_loc.nil?) &&
(message_loc.nil? == other.message_loc.nil?) &&
(read_name === other.read_name) &&
(write_name === other.write_name) &&
(operator_loc.nil? == other.operator_loc.nil?) &&
(value === other.value)
end
Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.

Sometimes you want to check an instance of a node against a list of classes to see what kind of behavior to perform. Usually this is done by calling ‘[cls1, cls2].include?(node.class)` or putting the node into a case statement and doing `case node; when cls1; when cls2; end`. Both of these approaches are relatively slow because of the constant lookups, method calls, and/or array allocations.
Instead, you can call type, which will return to you a symbol that you can use for comparison. This is faster than the other approaches because it uses a single integer comparison, but also because if you’re on CRuby you can take advantage of the fact that case statements with all symbol keys will use a jump table.
