  Optimize and analyze matches based on their TreeMaker-representation.

  Optimize and analyze matches based on their TreeMaker-representation.

  The patmat translation doesn't rely on this, so it could be disabled in principle.

  - well, not quite: the backend crashes if we emit duplicates in switches (e.g. scala/bug#7290)

   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): (SwitchMaker, B)

   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.
