Ask HN: What should be added to the syntax of Python and why?

Ditch the general purpose variable annotations thing and make strong typing types first class
Curly braces, to make whitespace insignificant. I don't like significant whitespace.
I don't know the name of this idiom, but the following is valid Python:
import pandas as pd
my_df = (
I also use plotly like so:
my_plot = (
Not exactly function chaining, but I guess it has a similar effect.
I'm happy with Python's syntax nowadays and much prefer seeing improvements on library / environment related things.

pd.Dataframe(<fetch_data>)
.join(<...>)
.query(<...>)

It's called a fluent interface.
I want braces.
I would love separate variable initialization vs assignment. I know that ship has sailed.
It's interesting, I never cared about that until I did "Crafting Interpreters" and realized how separating those two actions helps clarify scopes.
Being realistic I know it's too large of a breaking change and will never land in the language but I can dream right?

None propagation. It such a pain to constantly check for None when accessing very deep nested structures (as I had to do often with JSON data).
There is a PEP for this[1] but it is currently deferred.

Multi-line lambda. It would be more easier to use than cramming a piece of code into a single line.
I know in Lisp languages you can extend the syntax easily, but I was wondering if there are any needs for that in Python.
