In literally your first answer you resorted to aggressive language and 
implied that what I asked wasn't what I actually wanted. It was.

Also note that in your first answer you did not answer "sorry, this is 
not possible", which would have been completely sufficient as an answer. 
Instead you tried your best at guesswork, implying I didn't know what I 
was doing.

So, yes, absolutely toxic behavior. I fully stand by that judgement of mine.

I'll go a step further and again repeat that THIS sort of behavior is 
what gives open source forums a bad rep. There's always a Lennart 
Poettering, an Ulrich Drepper or maybe a Chris Angelico around who may 
have great technical skill but think they can treat people like shit.

LOL, "ban you"? What the heck are you talking about, my friend?

I don't need to be coddled by you. I'm trying to give you the favor of 
honest feedback, which is that you sound like an utter bully. If you 
don't care, that is totally fine by me.

Yeah that sucks, unfortunately. But I'll live.

Does format_map do exactly what f-strings can do? Can I pass arbitrary 
functions and Python expressions insode a format_map? No? Of course not. 
Then it does not answer the question.

Awww, it's adorable how you're trying to frame yourself as the victim. 
I'll be here if you need a hug, buddy.

Yeah we'll have to disagree about the fact that it's the "laws of 
physics" preventing a specific implementation of a Python function.
