This commit changes the behavior of KT-59138 effectively declining it in 2.0.
However, we plan to implement KT-59138 behavior under a feature
flag in 2.0 (see KT-66447), and switch this feature on version 2.x.
Also, this commit implements the LC resolution about postponing
KT-57014 change. We don't have KT-57014 described behavior in 2.0 anymore.
However, we plan to implement a deprecation warning here, see KT-65578.
After this commit, 6 diagnostic tests become incorrectly broken:
- 5 tests from PurelyImplementedCollection group
- a test platformTypes/nullableTypeArgument.kt
This commit also breaks currently fixed-in-k2 KT-50134
(it is fixed again in the following commits),
as well as KT-58933 (it will remain not fixed till we enable KT-59138
behavior again).
#KT-65596 In Progress
#KT-57014 In Progress
#KT-58933 Submitted
This fixes some type argument mismatch errors caused by a captured type
being approximated and then captured again.
Some places need to be adapted to work with captured types that
previously only worked with approximated types.
#KT-62959 Fixed
```
open class Base<T> {
fun foo(): T = ...
}
class Derived<T> : Base<T> {
override fun foo(): T = ...
}
```
In intersection scope of type `Base<T> & Other<R>` we should create
intersection override based on `Base.foo(): T` and `Derived.foo(): R`
at the same time, despite the fact that `Derived.foo` actually directly
overrides `Base.foo`
