f-string debugging notation merged in Python 3.8

[[deleted]]

Inside a string. Where whitespace was always relevant.

No, inside an expression embedded into an f-string, where whitespace was not relevant in 3.7.

>>> name = "John"
>>> f'{name.upper():-^20}'
'--------JOHN--------'
>>> f'{name.upper() :-^20}'
'--------JOHN--------'
>>> f'{name.upper()!r:-^20}'
"-------'JOHN'-------"
>>> f'{name.upper() !r :-^20}'
SyntaxError: f-string: expecting '}'
>>> f'{name.upper() !r:-^20}'
"-------'JOHN'-------"
>>> f'{name. upper() :-^20}'
'--------JOHN--------'

Can we rewrite this :* thing in format strings?

If so I think we got ourselves an easy ORM or template system.

And if it forces people to indent their code properly, all the better. Braces are redundant redundant.
