> Since these classes are writeteable, they need a buffer in order to stage pending changes
for efficiency reasons. The issue is that at read-time, the code then needs, for every call
to {{get}} to check whether the requested value is in the buffer of pending values or has
been packed into main storage, which is inefficient.
> I would like to fix these APIs to separate the writer from the reader, the latter being
immutable.
