That works, as does this:
if(stu == Student.init)
Structs are a value type and will always have a type that won't be null.
If you want it to be nullable you will have to use pointers or classes
(there is also Nullable in std.typecons but it won't work with is null).
s/have a type that won't be null/have a value that won't be null/
My bad.
