Track Rust progress

Collection of items the author is interested to see the status of.

`gen` in edition "2024"?

Tracking issue for gen blocks and functions

Can by tried, with:
```
 # cargo.toml
 edition: "2024"
 #![feature(gen_blocks)]
```
- Make a sample in the flakes :)

Getting `stream` into the `std::` module

Do we need it to be?

Do futures-rs and tokio provide enough?

`spmc` channel?

Last (2024) entry of "add an mpmc channel"

The Pool approach could benefit from this.
