as of 2020 (PEP 638), python has macros (but they're still slightly janky). Before that there were decorators which look kind of similar but are a lot less powerful.
- nerpderp82 4y agoAre they implemented anywhere? It looks like the PEP is draft. You can do all the macro like things you want using framehacks and eval at the top level. Where they are hard to apply w/o direct support is down inside some function. Then you have to bytecode patch the result on first execution.

- BerislavLopac 4y agoNot just decorators, but all kinds of functionalities that allowed types to be constructed at runtime.
