Nulls.jl is a very simple package: it provides a single type
Null with a single instance
null. It also defines basic operators on
null so that it essentially becomes a
NaN for any type. e.g.
null < 1 == false and
null == 1 == false. It is also not dissimilar to the type
Void with single instance
nothing in Julia. The difference is where
nothing is used as, for example, the return type of
null has more operations defined and conceptually is used to represent missing values in data.
