# Delambdafy

#### abstract class Delambdafy extends SubComponent with Transform with TypingTransformers with TreeDSL with TypeAdaptingTransformer

This transformer is responisble for turning lambdas into anonymous classes. The main assumption it makes is that a lambda {args => body} has been turned into {args => liftedBody()} where lifted body is a top level method that implements the body of the lambda. Currently Uncurry is responsible for that transformation.

From a lambda, Delambdafy will create 1) a static forwarder at the top level of the class that contained the lambda 2) a new top level class that a) has fields and a constructor taking the captured environment (including possbily the "this" reference) b) an apply method that calls the static forwarder c) if needed a bridge method for the apply method 3) an instantiation of the newly created class which replaces the lambda

TODO the main work left to be done is to plug into specialization. Primarily that means choosing a specialized FunctionN trait instead of the generic FunctionN trait as a parent and creating the appropriately named applysp method
