You totally don't get it. You describe how python is now.
I propose a change to be made to python. Small wonder that that is
different from what it is now.

You prove nothing by giving examples.
You can disprove by giving one counter example,
here it goes.

Whitespace (internal to a line) is significant.
In Python you cannot change
      xleftgoing = 123000000
to
        x left going = 123 000 000

(You can in Algol68)

What is a bad idea?
Apparently you are not talking about my idea of changing the parser.
("Pythons parser won't stop you from changing the parser" doesn't
make sense.)

As other languages have an Eleventh Commandment against concatenating
operators, the larger issue is hardly futile.

I'm having a great time, thank you!
