Smalltalk is highly dynamic, it keeps surprising me Python gets put into some kind of special place as excuse why people keep failing at JIT adoption.

Everything is a message, the meta classes that define object shapes can change any time some feels like it, there are methods like becomes: that completely replaces an object across all its references on the running image, break into debugger and redo after whatever was changed while into the debugger, code loaded over network,....

As if PyPy and GraalPy didn't even exist as well.
