This help me to understand your point of view.
But if I consider your proposition, it's evident that a simple comment `#
IDE:refactor` would not be enough for IDE. Because a string is full of words
and several of them could matchs the symbols of your code; by the way, the IDE
would not be able to delimitate expression. So you would have to put redondant
information into your comment, and redundancy is not cool for the user; if the
shortcut `f"{foo=}"` has been introduced in 3.8, that's to avoid "to repeat
yourself" (word taken from feature author).
By the way, there is (as far as I know) no comment standardisation in Python,
they are specific to the tools which use them. See how many docstring standard
we have; Both Pycharm and Black have their own comment directive to toggle
formatting on/off; when mypy and flake8 find an issue in your code, you have to
put # type: ignore # noqa… How could an approach using comment be promising?
And as you can see in other responses to your post, when the Python language
introduce a feature, IDEs adapt to fully support it. That's the case for
f-string where refactoring, linting, type-checking, reformatting, etc. are
handled inside. This is the difference between a literal string and a
"not-evaluated" string.
