False positive for no-empty-first-line check with function that returns an anonymous implementation

[lwasyl]

For the following code:

interface Foo {

    fun foo()
}

fun fooBuilder() = object : Foo {

    override fun foo() {
        TODO()
    }
}

KtLint complains for the empty line after Foo { and before override with experimental:no-empty-first-line-in-method-block] First line in a method block should not be empty. This is a false positive, since that empty line is not part of the function declaration, but of a class declaration.

What can be used now to ensure there is no empty line after Foo { and before override?

@idntfy most probably it is required new rule, please open a separate issue

[lwasyl]

@idntfy Do you want to treat anonymous classes differently than regular classes?

[idntfy]

I want everything to be treated the same way, for me it seems this issue proposes to treat it differently by allowing empty line for anonymous classes while not allowing it in other places
