Documentation states classes must override `toHash`/`opEquals`/`opCmp` to work
as associative array keys. But current implementation works anyway.
As people are lazy I suppose lots of such classes are already used as
associative array keys.
So once e.g. compacting GC will be implemented and `Object`'s `toHash` equality
will stop being class instance address equality current AA implementation will
start using `Object`'s `opCmp` which will throw thus breaking lots of code.
I'd suggest to either document such usage or check in AA implementation that
required functions are overriden.
