Indentation does not automatically indicate a statement, either. Why
do you omit semicolons?

So you do agree colons are line noise? Colons are unpleasant for me
not because I have to type them (though this certainly is a factor,
too), but I have to *read* them every time I read Python code and they
disrupt the mental flow.
You are assuming colons improve readability, which I disagree.
Readability comes from indentation, not from punctuation. If you logic
holds, you might have to use semicolons as well.
