3.0.0-RC1 release page mentions "Allow with after class #11157" in the Syntax section, and I think this is NOT right.
#11213 already reverted #11157.

Here is the final decision of keep using :: https://contributors.scala-lang.org/t/feedback-sought-optional-braces/4702/588.

@ShapelessCat I can do it in the repl

Scala compiler version 3.0.0-RC1 -- Copyright 2002-2021, LAMP/EPFL
scala> class Foo with
     |   def foo = 23
     | 
// defined class Foo

scala> Foo().foo                                                                                                        
val res0: Int = 23

@bishabosha Does this mean the after classes with syntax is a syntax that we plan to remove, but we haven't removed it completely?
I can also see a discussion in Add RC1 blog article #11417.

@ShapelessCat I am not sure what's happening, but thank you for linking to the discussion, I added my example there.
