Hi guys,

Thanks a lot for answers. I suppose I will not use any workarounds for now.

Best Regards,

I hope that you are expressing some form of sarcasm, Joe.

If I may use such language, it is horrible. Just as we got (almost) rid of {M,F} to the benefit of proper function references, are we going to get another kludge? A proper module reference is the way to go here. Then there are plenty of nice things that can be supported in a clean way.

best regards,
Vlad
