There is no need to modify a copy; only the Nullable is immutable and not
its underlying value. Just instead of modifying ec.title, modify
get(ec.title). Like setfield!(get(ec.title), k, v). In short scripts, I
often define getindex(x::Nullable) = get(x) so that I can write ec.title[]
instead o
So get() to check if a value is there, and if there is modify a copy then
overwrite?
If that's the case, it might be worth the mental overhead to use Nullable
types when mentally I'm viewing everything as a consistently mutating
object until the desired result is achieved.
