Note that like #type, it will still be slower than using == for a single
splitting on the type of the node without having to do a long === chain.
Similar to #type, this method returns a symbol that you can use for

these approaches are relatively slow because of the constant lookups,
case statement and doing `case node; when cls1; when cls2; end`. Both of
calling `[cls1, cls2].include?(node.class)` or putting the node into a
