### Deprecated Value Members

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

     This member is added by an implicit conversion from CommentPreservingTypers toStringFormat[CommentPreservingTypers] 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): (CommentPreservingTypers, B)
   Implicit
     This member is added by an implicit conversion from CommentPreservingTypers toArrowAssoc[CommentPreservingTypers] 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.
