New incompatibility: case class companions don’t extend Function anymore about scala-3-migration-guide

[adpi2]

As a work-around, we can also use the apply method because it can be eta-expanded to a Function2

Foo.apply.curried(1)(true) // compiles in Scala 2.13 and Scala 3.0.0-M3

What do you think @julienrf ?

[adpi2]

Actually it doesn't compile in Scala 2.13:

[error] Unapplied methods are only converted to functions when a function type is expected.
[error] You can make this conversion explicit by writing `apply _` or `apply(_,_)` instead of `apply`.
[error]   val foo1 = Foo.apply.curried(1)(true)

But this one cross-compiles:

(Foo.apply _).curried(1)(true)
