If I understand correctly, “Missing” has become an important part of Julia’s future. (keeping 1.0 delayed, too.) I think this makes a lot of sense.
Right now, we have “Real”, “AbstractFloat”, and “Integer” as convenient type catchers for the most important categories of numbers (Ints+Floats, Floats, Ints). Is there a plan to have similar type catchers for these but with Missing Union, or does everybody have to program this themselves?
