There was a problem hiding this comment.
I think this is not what's desired, the enclosing method should be tb. The EnclosingMethod attribute (aka OUTERCLASS) should represent the source level view.
There's a very long comment here: https://github.com/scala/scala3/blob/3.4.2/compiler/src/dotty/tools/backend/jvm/BTypes.scala#L341
There's a test suite for InnerClass / EnclosingMethod attributes at https://github.com/scala/scala/tree/2.13.x/test/files/jvm/innerClassAttribute which was not ported 1:1 to scala 3, but @prolativ worked on the attributes in #11589.
The anonfun "() => new TB {.." code is lifted to a static method, in the
original class (A), but the GenBCode logic was still returning the TA
anon class.
