Ian wanted something to dynamically get sets of keys.

require 'pp'

$glob_store = []

def get_key_sets(temp, previous_set = nil)
	temp.each_with_index do |value, index|
		if previous_set.nil?
			new_set = []
		else
			new_set = previous_set.dup
		end
		new_set << index
		$glob_store << new_set
		if value.is_a? Array
			get_key_sets(value, new_set)
		end
	end
end

temp = [
	[
		[
			9,
			8,
			[
				9
			]
		]
	],
	[
		0,
		2,
		4
	]
]

get_key_sets(temp)

puts; puts; puts;
$glob_store.each do |key_set|
	puts key_set.join("->")
end
puts; puts; puts;
