  This transformer is responsible for preparing Function nodes for runtime, by translating to a tree that will be converted to an invokedynamic by the backend.

  This transformer is responsible for preparing Function nodes for runtime, by translating to a tree that will be converted to an invokedynamic by the backend.

  The main assumption it makes is that a Function {args => body} has been turned into {args => liftedBody()} where lifted body is a top level method that implements the body of the function. Currently Uncurry is responsible for that transformation.

  From this shape of Function, Delambdafy will create:

  An application of the captured arguments to a fictional symbol representing the lambda factory. This will be translated by the backed into an invokedynamic using a bootstrap method in JDK8's `LambdaMetaFactory`. The captured arguments include `this` if `liftedBody` is unable to be made STATIC.

   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.

     (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.
