ImmutableStructEx is yet another immutable struct. What makes ImmutableStructEx different, is that it allows you to create immutable structs in one step by default. In other words, other immutable struct gems force you to first define the struct, then instantiate the struct object; or, define the struct and instantiate the struct object via chaining.
