93/// The journal effector is an adapter that will be removed in a future refactor.
94/// Its purpose is to put the code that does mappings from WASM memory through its
95/// abstractions into concrete journal objects that can be stored. Instead of this
96/// what should be done is that the syscalls themselves can be represented as a
97/// strongly typed object that can be passed directly to the journal but in order
98/// to do this we require an extensive refactoring of the WASIX syscalls which
99/// is not in scope at this time.
100///
101/// Separating this out now makes it easier to eliminate later without hurting the
102/// journal event abstraction through leaking abstraction layers.
