        # Array.any?

(from ruby core)
---
    array.any? -> true or false
    array.any? {|element| ... } -> true or false
    array.any?(obj) -> true or false

---

Returns `true` if any element of `self` meets a given criterion.

With no block given and no argument, returns `true` if `self` has any
truthy element, `false` otherwise:
    [nil, 0, false].any? # => true
    [nil, false].any? # => false
    [].any? # => false

With a block given and no argument, calls the block with each element in
`self`; returns `true` if the block returns any truthy value, `false`
otherwise:
    [0, 1, 2].any? {|element| element > 1 } # => true
    [0, 1, 2].any? {|element| element > 2 } # => false

If argument `obj` is given, returns `true` if `obj`.`===` any element,
`false` otherwise:
    ['food', 'drink'].any?(/foo/) # => true
    ['food', 'drink'].any?(/bar/) # => false
    [].any?(/foo/) # => false
    [0, 1, 2].any?(1) # => true
    [0, 1, 2].any?(3) # => false
