[Python-ideas] Re: Extract variable name from itself

[Dom Grigonis]

An addition to f-strings:
a = 1
b = 1
print(f'{a+b}')     # '2'
print(f'{a+b=}')     # 'a+b=2'
# I suggest adding this too
print(f'{=a+b}')    # 'a+b'
It is different from putting it in quotes in a way how editors interpret it. 
E.g. changing the variable name in PyCharm would unambiguously change f-string 
as well, while it would not change the string literal.

Also, one could argue that it can just be extracted by 
`f’{a+b=}’.split(‘=‘)[0]`, but it is of course sub-optimal given the 
possibility that evaluation is expensive and not required.
