    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 scala.reflect.internal.AnnotationInfos.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.

### Deprecated Value Members

1.  def formatted(fmtstr: String): String

     This member is added by an implicit conversion from JMirrorBuilder toStringFormat[JMirrorBuilder] performed by method StringFormat in scala.Predef.
   Definition Classes
     StringFormat
   Annotations
     @deprecated @inline()
   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.

2.  def →[B](y: B): (JMirrorBuilder, B)
   Implicit
     This member is added by an implicit conversion from JMirrorBuilder toArrowAssoc[JMirrorBuilder] performed by method ArrowAssoc in scala.Predef.
   Definition Classes
     ArrowAssoc
   Annotations
     @deprecated
   Deprecated

     (Since version 2.13.0) Use `->` instead. If you still wish to display it as one character, consider using a font with programming ligatures such as Fira Code.
