[New-bugs-announce] [issue43695] Improve `=` in f-strings

[wyz23x2]

New submission from wyz23x2 <wyz23x2 at 163.com>:

In Python 3.8, `=` was added into f-strings:
>>> a, b, c = 20, 40, 10
>>> f'{a+b-c=}'
a+b-c=50
But if `20+40-10` is wanted, this needs to be written:
>>> f'{a}+{b}-{c}={a+b-c}'
20+40-10=50
So something could be added. For example, `?` (this doesn't mean I recommend the question mark):
>>> f'{a?+b?-c?=}'
20+40-10=50
>>> f'{a+b?-c=}'
a+40-c=50
>>> f'{a+b-c=?}'  # Suffix `=` to apply to all?
20+40-10

Suggestions?
