One thing I vastly dislike with them is that they are still expanded in logging, while they are not expanded when logging is using "the old way".

What do you mean the old way?

Will it print what foo is if I type logger.info("{foo=}")?

Logging.info(“%s %s”, name, country”) the string isn’t expanded if the logging is set to warn. While with your example the string is expanded then discarded

How would you fix the issue without breaking existing semantics?

The way I see it, it's a necessary price to pay, and I just continue to use c-style forming strings in logging.

The clean way would be to introduce laziness. But yeah, can't do that in Python.
