How Many Lines of C It Takes to Execute a and B in Python?

It’s not entirely true that JS does not have magic methods. `valueOf` and `toString` can show up surprisingly deep into the resolution of operations, and recent JS has “well known symbols” to implement or override behaviour.

However it is true that this is much, much less extensive than it is in Python. As of 3.12, section 3.3 (“special method names”) of the data model documentation lists 107 entries (although some of them only apply to class protocols, and a handful are duplicates for async versions / context of sone operations).

`valueOf` and `toString` are indeed fairly complex (and it's fun to consider when both are implemented ;-), but less of concern for tracing JIT engines because you can have efficient type-specialized implementations for most cases. Type specialization in Python is not that huge win...
