Using id() is a workaround but again, a potentially expensive one for platforms with moving GCs. Every object calling for an id() forces additional bookkeeping on their ends. This is only a better solution for CPython.
Well, CPython and all other implementations with a non-moving GC.
Whereas abstracting this out into an identitydict type gives all platforms the chance to provide their own optimized versions.
That's really premature optimization. Regards Antoine.
