No, good catch. The original has a teardown method to convert the tree back to a list and verify he result, but I don't think it's measured as part of the benchmark iterations.

This is a benchmark both WebKit and V8 have used to measure their GC.
CRuby seems to perform pretty badly at this particular benchmark, and with a very large standard deviation. Although Ruby 4.0 does seem reliably faster than 3.4.
I vibe-ported this as directly as possible. For the
generate_payloadbeing inserted I made all the intermediate nodes a PORO with the leaf node containing a hash, array, and interpolated string.
