using JSON3

struct Foo{I<:Union{Nothing,<:Number}}
  name::String
  value::I
end

serialized_ = JSON3.write(Foo("test", nothing))
deserialized_ = JSON3.read(serialized_, Foo) # if this runs first, both `read`s fail

struct Bar{I<:Union{Nothing,Number}}
  name::String
  value::I
end

serialized_ = JSON3.write(Bar("test", nothing))
deserialized_ = JSON3.read(serialized_, Bar) # if this runs first, both `read`s succeed
