Ruby offers a super convenient method for sorting complex objects in Enumerable#sort_by. But when sorting by multiple conditions or dealing with potential nil values, things get messy in a hurry.
This video shows off a common (but little-discussed) technique for building `sort_by` blocks that return prioritized arrays of values and then demonstrates how our new Put gem can accomplish the same thing with a cleaner and more expressive API that provides nil safety.
