[New-bugs-announce] [issue29894] Deprecate returning a subclass of complex from __complex__

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

This is similar to issue26983, but complex() always returned exact complex. A deprecation warning is added just for uniformity with __float__ and __int__.
