New and Exciting Features Planned for Python 3.4

With the alpha releases slowly trickling out, we have a pretty accurate idea of the new features that Python 3.4 will include. The additions and big changes we know of so far are:

  • a standardized "enum" module
  • improved semantics for object finalization
  • adding single-dispatch generic functions to the standard library
  • a new C API for implementing custom memory allocators
  • changing file descriptors to not be inherited by default in subprocesses
  • a new magic method for metaclasses (__typelookup__)
  • making automatic sequence unpacking more general
