 Note that Python 3.6 was only officially released two days ago :-)

 And unfortunately it's not just a matter of adding the version to the py-
 readline port.

 With a (locally generated) py36-readline installed:
 {{{
 MacPro:~ fw$ python3.6
 Python 3.6.0 (default, Dec 23 2016, 12:59:30)
 [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)] on darwin
 Type "help", "copyright", "credits" or "license" for more information.
 >>> 1+1
 Python(59962,0x7fff7a4d0310) malloc: *** error for object 0x103e7f640:
 pointer being freed was not allocated
 *** set a breakpoint in malloc_error_break to debug

 }}}

 Without it:
 {{{
 MacPro:~ fw$ python3.6
 Python 3.6.0 (default, Dec 23 2016, 12:59:30)
 [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)] on darwin

 }}}
 The latter shows the usual trouble until "stty sane" (unechoed).
