Reference to implicit variable [message #821018]

I'm trying to implement implicit variables, see this groovy snippet:

  
  names = someList.collect{String item -> item.toLowerCase()}
  names = someList.collect{it.toLowerCase()}

They are equivalent, the first case is explicit, the second implicit.

My idea is to handle it with a custom scope provider:

  MyScopeProvider extends AbstractDeclarativeScopeProvider {
    public IScope scope_Id(FeatureWithClojure owner, EReference ref) {
      // ?
    }
  }

My questions are:

Is this a correct approach? Or what else would you suggest?
How can I create a scope that already has the implicit variable "it" registered into it.

thank you, Adam
