Thank you, It is a great honor to see my name on the list.

You deserve it.

@pablogsal are you OK with this going into 3.11 whats new? Or would you prefer I host this somewhere else and link to it in the whatsnew?

For the time leave it here in its own section as in this way I will be able to easily do the final edits. Removing or moving information is much easier to add it as that way I don't need to consider what may be missing :)

Also, it's not clear for what operation you are claiming a 170% speedup (so a factor 2.7). The table layout makes it look like C(arg). But surely the speedup for class constructors is not a single extremely large number?

Oof the table layout worked against me. The 170% speedup is tied to "Calls to certain python functions are inlined", not C(arg). I have since removed that line altogether.
