I was talking about syntax. I'm pretty sure there will be new features that will require a new keyword or syntax given the speed of Python growth. It can be universal, for example same as decorator, but it can be applied anywhere.

   from lazy import make_lazy
   from package import module @make_lazy @local @nogil

Let's say this syntax gets introduced in Python 3.16. The @nogil feature can be introduced in 3.17. If such code is running in Python 3.16, the @nogil marker will be ignored.

The problem with new keywords is that you have to stick to the newest Python version every time a new keyword is added. Older Python versions will give a syntax error. It's a big problem for libraries. You need to wait for 3-5 years before adding it to a library. There are a lot of people who still use Python 3.8 from 2019.
