Thanks, but :-). Two comments (related): 1. in that particular case, you're doing it not really because you want to dynamically define your global function, but because you need the lexical closure (your let is at the top-level). How about non-functional variables? 2. also, technically, your lexical closure isn't required for the function itself, but for the particular method you're defining. But I guess there's no way of declaring an empty generic function? -- ELS'16 registration open! http://www.european-lisp-symposium.org Lisp, Jazz, Aïkido: http://www.didierverna.info
