WARNING: physical comparison is used by the container.
CONSEQUENCE 1: should be used with caution to store int32,
int64, nativeint, or double values as they are wrapped into
blocks. Hence, comparisons are done on block addresses rather than
on wrapped values.
CONSEQUENCE 2: as OCaml-Java uses boxed values for int values,
the container should not be used to store int values.
Any other type can be safely stored (caching of some int values
ensure that sum types are correctly handled).

faster on some platforms, but does not provide ordering guarantees.
