-The details of the impplementation are quite interesting to me, so you might want to give the [PR](https://github.com/python/cpython/pull/140310) a read. The key idea is to maintain two dispatch tables in a mechanism I call "dual dispatch". One table is the standard interpreter, the other is the tracing interpreter. we (ab)use computed gotos/tail calling to dispatch from one table to the other.
