The linked LWN article[1] mentions context-sensitive keywords, ie. a way to treat certain words as language keywords only in specific contexts. For example, a new match statement that wouldn't require reserving the `match` word as a language keyword, which would require a breaking change and break all existing code that uses `match` as a variable name.

Such a feature requires support from the parser.

One good example (for those who do not want to read the full article) is the async keyword. Introducing it as keyword broke a few libraries which were already using them as kwarg in some functions (e.g. pytorch).

I wonder if Python will go back and address other shortcoming which I assume are tied to the parser, such as the inability to use quotes inside the interpolated segments.
