As Scala 2 macros were an experimental feature, they were not included in the spec, and the macro keyword is still a keyword there is thus nothing to do (Scala 3 macros will get their own commits through the corresponding pages)
Scala 3 does not infer more precise types for the return type of overriding methods.
This can be seen in the following example:
```scala
type T
type U <: T
abstract class A{
def m: T
}
class B extends A{
def m = ??? : U
}
val res: U = (new B).m
```
As the feature is not actually deprecated, no changes to the spec are needed
Will make it easier to explain later what happens when you apply a using method to explicit parameters

There was a problem hiding this comment.
I think that section should be dropped from the spec, IMHO it belongs to the migration guide.

@julienrf Did you intentionally push the "Wildcard Types" commit to this PR branch? |
|
Yes, I wanted to shape this PR to a mergeable state. |

This is the rest of the work I did on the Spec, it is not in individual PRs, but still follows the other principles outlined in #16839 and in
