Multidispatch-friendly zen of unzip in julia

@ https://gist.github.com/o314/214e26c6fb70512b56597d633dd87e6f
see JuliaLang/julia#13942

OK unzip(a) = zip(a...) fails in Julia But Zen of python is great - ok, it's somewhat a lie, it's also great for julia ! So let's try to bring correct simple things first, and (maybe) complicated ones later or away.

FWIW, my good-enough-poor-man, but usable in prod, isn't it, unzip considering than

Write a class Greed with a score() method that accepts an array of die values
(up to 6). Scoring rules are as follows:

A single one (100)
A single five (50)
Triple ones [1,1,1] (1000)

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

Design rules
