main has pretty resonable support for returning values directly since pointer tagging happened. we should remove out parameters from all signatures and return proper values instead.

  • Expr::eval
  • primops
  • EvalState::callFunction
  • EvalState::autoCallFunction
  • EvalState::concatLists
  • EvalState::eval*
  • EvalState::mk*
  • Evaluator::evalLazily
  • getDerivation
  • parseJSON

and numerous others probably
