Here are some idioms I can imagine a use for with IdentityObject:
// parameter type
void withLock(IdentityObject monitor, Runnable task)
// type bound
Map map = ... // gonna lock on keys
// dynamic check
if (x instanceof IdentityObject) {
sync (x) { task(); }
There is a 3rd way, uses the TypeRestriction attribute to still be binary
backward compatible.

like
import ...
__restrict__ java.lang.IdentityObject __to__

If it's possible, i would like to discuss about IdentityClass again.
As noted in the last draft, adding IdentityClass automatically at runtime is
not a compatible change if tests that uses Class::getInterfaces() are not
written correctly,
and sadly, a lot of tests are written that way. I'm
