Is there a similar command to install whatever the latest Python 3 version is? For example:

`sudo pkg install python3`? 

It'd be good to be able to not have to update the docs when Python 3.5 comes out. 

(A similar thing applies to `python27` but [there will be no Python 2.8](http://legacy.python.org/dev/peps/pep-0404/).)
