class, but should be faster in a case statement or an array comparison.
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

you can take advantage of the fact that case statements with all symbol
it uses a single integer comparison, but also because if you're on CRuby
can use for comparison. This is faster than the other approaches because
Instead, you can call #type, which will return to you a symbol that you
method calls, and/or array allocations.
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
classes to see what kind of behavior to perform. Usually this is done by
Sometimes you want to check an instance of a node against a list of
