      • derive from ABTOpDynamicArity<0>
      • the constructor accepts a vector of pairs of ABT node, plus a final ABT node, that are stored in the flat vector inherited from ABTOpDynamicArity
      • add the new type to the known walkers, using the logic used for the If node as a template:
        • SBEExpressionLowering
        • ExplainPrinter
        • LastRefsTransporter
        • ExpressionConstEval
        • TypeChecker
        • Vectorizer
        • ValueLifetime
      • add unit tests for the walkers to test the new logic
      • change buildABTMultiBranchConditionalFromCaseValuePairs so that it creates the Switch node if the feature flag is set to true
