One advantage is maintaining control over the __init__ function
without having to write extra code to do so. In the linked discussion
from python-ideas, it was mentioned that keyword-only a

Two questions here.
Firstly, does anybody know of existing discussions (e.g. on here or on
python-ideas) relating to unpacking inside lambda expressions?
I found myself wanting to write the following.
```
map(
lambda (module, data): result.process(module, data),
jobs
)
```
However, it's

I intend to take this to python-ideas, but I'm not currently subscribed
there and I think I should probably do a bit of research before
proposing something over there. So I'll start by gathering some feedback
