Casting to immutable is the only way to create such a beast.
Then maybe we have to improve the language semantics to allow a better
solution. See the Transients of Clojure or the larval objects of Java :-)
The compiler may need to test (at compile time) that there's only one
reference to the AA and its contents, and turn it into immutable.
Or, we can make array literals (including AA's) immutable, and call it a
day.
The only thing is that AA literals provide a nice syntax to make
non-immutable AAs also, and I can't think of a good way to make a library
function that creates an AA. Anyone have any ideas?
