If you write code like this:

  if x:
      # do stuff
  # do other stuff

Your indenter will not know where to put the third line.

In languages whose blocks are closed using nonwhitespace the problem doesn't exist. Your indenter just has to push everything as far to the right as it can, and problem solved.

It's nice that your editor gets copy and paste right, but it doesn't and indeed can't decide how to indent your code, something that works in every other language I've dealt with.

Why does that matter?

In brace language:

if (condition) {{ code_1 }} code_2

In Python:

if (condition):\n code_1 \n^H code_2

Unless your editor also knows when to place your close braces, and, haha, it doesn't and indeed can't, you have not even won a keystroke.

Once I've placed my closing braces, I'll never need to think about it again, unless and until I restructure that piece of code.

It's got nothing about saving keystrokes.

And now, back to working on pass-infested Python code.
