was there problems?

@youknowone I was doing some yak-shaving to bump the typing module, and then I wanted to bump the RustPython parser, and this is where I realized my lack of understanding of the PEPs involved and my lack of understanding of the underlying parser (compiler).

Due to personal situation, I'm a bit confused about my study priorities and lack motivation.

At the same time, new PR (#5590) had opened and I didn't want it to look like someone was working on them, so I closed PRs to avoid confusion.
