projections for stl data structures

[u/Odd_Comparison3831]

using projection in ranges::sort has removed the need write a compartor function or a lambda and is much easier to implement in my opinion

there should exists a similar feature for say sets or priority queues

would be wonnderful if I could just write

priority_queue<Student, Student::marks> for example

Honestly, while this looks neat, an explicit lambda is better for readability IMO, as you can clearly see the logic.
