    Annotations are not processed by the compilation pipeline like ordinary trees.

    Annotations are not processed by the compilation pipeline like ordinary trees. Instead, the typer extracts them into AnnotationInfo objects which are attached to the corresponding symbol (sym.annotations) or type (as an AnnotatedType, eliminated by erasure).

    For Scala annotations this is OK: they are stored in the pickle and ignored by the backend. Java annotations on the other hand are additionally emitted to the classfile in Java's format.

    This means that Type instances within an AnnotationInfo reach the backend non-erased. Examples:

    - @(javax.annotation.Resource @annotation.meta.getter) val x = 0 Here, annotationInfo.atp is an AnnotatedType.
    - @SomeAnnotation[T] val x = 0 In principle, the annotationInfo.atp is a non-erased type ref. However, this cannot actually happen because Java annotations cannot be generic.
    - @javax.annotation.Resource(`type` = classOf[List[_]]) val x = 0 The annotationInfo.assocs contains a LiteralAnnotArg(Constant(tp)) where tp is the non-erased existential type.
