…which is just a fancy way to say that this works like I think it should:
>> [['foo', 1], ['bar', 2], ['honk', 1000]].partition { |str, val| val > 999 }
=> [[["honk", 1000]], [["foo", 1], ["bar", 2]]]
Which beats the pants off this:
>> [['foo', 1], ['bar', 2], ['honk', 1000]].partition do |pair|
?> str, val = pair
>> val > 999
>> end
=> [[["honk", 1000]], [["foo", 1], ["bar", 2]]]
So, you see, the array elements get unpacked into @str@ and @val@ inside your block. Which is unexpected, but totally and thoroughly lovely. To my eyes, the former is much easier to read.
