Hi Tamas,
I would like to come back to your argument (the missing value theme for me is in principle through)…
… you only convince the development community of Julia. You can only convince users who want to model mathematical problems or - like me - perform data analysis if Julia is easy to use, fast and stable. But if you say that you want to deal with missing values, you have to call this and that function in addition, the motivation is certainly not that high. Let me give you an example from another area (sorry for that): The car industry no longer advertises torque or overhead camshafts, but driving comfort and safety.
But I don’t want to stress it, I just want to give suggestions.
Cheers,
Guenter
