One of my hesitations on this topic is that it could create a false sense of

sense leading to insufficient testing, as well as 'we have a top-notch quality

Why? I can iterate over a string. [c for c in 'abc'] It certainly behaves like
one... I'd say this

The format of map seems off. Coming from JS, all the functions come second. I
think this approach is superior.
Currently:
map(lambda x: chr(ord('a')+x), range(26)) # ['a', 'b', 'c', 'd', 'e', 'f', 'g',
'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w',
'x', 'y', 'z'

I am a relative nobody in Python, however a few weeks ago, I suggested more
harmonization with JavaScript. Admittedly I've been doing more JS lately, so I
might have JS-colored glasses on, but it looks like you're trying to add
lexical scoping to Python, and there's a whole lot of manual scope w

Before I done my firesuit, I'd like to say that I much prefer python and I rail
on JS whenever I can. However these days it is quite common to be doing work in
both Python and Javascript. Harmonizing the two would help JS developers pick
up the language as well as people like me that are stuck w
I experimented with Python in college and I've been for close to 20 years now.
(Coming and going as needed) I love the language. But there is one annoyance
that I continually run into.
There are basically two assignment operators, based on context, = and :
a = 1
{ a: 1 }
They cannot be used
