我在对象中有一个对象数组，并尝试减少为特定形式的数组。例如：
[
#<Item name: "Item 1", content: #<Item value: #<Item quantity: val1>, #<Item
quality: val2>>,
#<Item name: "Item 2", content: #<Item value: #<Item quantity: val1>, #<Item
quality: val2>>,
#<Item name: "Item 3", content: #<Item value: #<Item quantity: val1>, #<Item
quality: val2>>,
#<Item name: "Item 4", content: #<Item value: #<Item quantity: val1>, #<Item
quality: val2>>,
#<Item name: "Item 5", content: #<Item value: #<Item quantity: val1>, #<Item
quality: val2>>
]
应该减少到
[ [Item1, [val1, val2]], [Item2, [val1, val2]], [Item3, [val1, val2]], [Item4, …
