[issue44703] deepcopy(frozenset()) returns a new object

[Raymond Hettinger]

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:

Returning the same object is just a micro-optimization and we've decided that it isn't worth it.  In bpo-40521, frozenset() stop being a singleton.  This costs a small bit of space but saves code complexity and a bit of execution time (especially given that we no longer have cheap access to global state).

Thanks for the suggestion, but we'll pass.
