   apply itself must render a faithful representation of the TreeMaker

   Concretely, True must only be used to represent a TreeMaker that is sure to match and that does not do any computation at all e.g., doCSE relies on apply itself being sound in this sense (since it drops TreeMakers that are approximated to True -- scala/bug#6077)

   handleUnknown may be customized by the caller to approximate further

### Deprecated Value Members

   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): (TreeMakerToProp, B)

     @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.
