Your reply appears to indicate that you do not properly understand the new proposed feature. It is most certainly not just about dropping two parentheses.

> Tag strings extract more than just a callable from the Interpolation. They also provide Python string formatting info, as well as the original text.

The feature is akin to moving print from a keyword to a function. That change also made a huge difference in that it unified the output stream and avoided having undefined objects like a "print" keyword.

Here, you can think of the feature as moving an "f" string from a hardcoded, predetermined definition to a generalizable and programmable behavior.

If "f" strings have become so popular so quickly it means they addressed a pressing need. It is logical to assume that a programmable version of an "f" string would be even more useful.
