    Description

      Currently @DelegateTo allows to use the generic type of another argument of the call, but I actually need to delegate to one of the generic parameters of the enclosing class.

      I.e. my signature is:

      PipelineBuilder<T> map(
           boolean passThroughNulls = true, 
           @ClosureParams(value=FromString.class, options=["T"]) Closure<T> mapper
      ) 
      

      And I want the mapper closure to be able to refer to the payload through the delegate as well as the 'it' parameter.

      Unfortunately @DelegatesTo won't let me do this as it was written prior
      to @ClosureParams and it does not support things like FirstParam or FromString...

      Aligning the config params of @DeleatesTo and @ClosureParams, will make them more powerful and easier to learn.
