This is pure and unadulterated FUD.
Nobody is going to use this as the standard way of writing classes. That
would be silly: you end up repeating the class name over and over and
And to say that this will happen "in a couple [of] months" is totally
unrealistic. Although, I suppose that if the entire Python community did
drop 2.7-3.6 and move to 3.7 within just one or two months so they could
use this syntax, that would certainly vindicate the (hypothetical)
decision to add this syntax.
But honestly, no. This is not going to happen. .Net VB and C# have
something like this, as does Lua, and people still write classes the
ordinary way 99.99% of the time.
The chances of this becoming the required, or even the recommended, way
to write methods is much less than the chances of President Trump
introducing Sharia law to the United States.

Do you *really* think that a linter that used to be called "PEP8" is
going to require as a default syntax which (1) doesn't work before
Python 3.7 at the earliest, and (2) has no support in PEP-8?
It's one thing to question whether this feature is useful enough to be
worth adding. It's another to make panicky claims that the Sky Will Fall
if it is accepted.
