        # Array.==

(from ruby core)
---
    array == other_array -> true or false

---

Returns `true` if both `array.size == other_array.size` and for each
index `i` in `array`, `array[i] == other_array[i]`:
    a0 = [:foo, 'bar', 2]
    a1 = [:foo, 'bar', 2.0]
    a1 == a0 # => true
    [] == [] # => true

Otherwise, returns `false`.

This method is different from method Array#eql?, which compares elements
using `Object#eql?`.
