How about these common operations?
my_string = my_string.replace('quite rare', 'very common')
my_string = my_string.upper()
my_string = my_string.strip()
my_dict = my_dict.copy()
Or from decimal, a whole lot of methods that return new decimals,
including:
to_integral, next_plus, canonical, ln, sqrt, and many others.
But regardless of whether the pattern x = x.method is common or rare, I
don't like the suggestion, I don't think it's necessary, and because of
the moratorium it isn't going to happen any time soon even if Guido
himself suggests it.
-1 for the suggested .= syntactic sugar.
