Lenny Maiorani d11727ff28 AK: Implement generic any_of algorithm
Problem:
- Raw loops are often written to validate that any values in a
  container meet a predicate, but raw loops are not as expressive as
  functions implementing well-named algorithms and are error-prone.

Solution:
- Implement a very generic form of `any_of`.
