Python has macros too.
- adgjlsfhk1 4y agoas 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.
- xiaodai 4y agowell. python has ALOT of stuff but alot of it is garbage compared to how they should be done. like python's lambda, you literally have to write the word lambda. it's ugly af i bet the python macros will be ugly af too. also walrus operator = bdfl no more.
