 * Create :foreach process plugin variants that do not handle multiples.
 *
 * For example, if the my_array is an array [4, 2]...
 *
 * @code
 * my_dest:
 *   plugin: evaluate_condition
 *   condition: greater_than(3)
 *   source: my_array
 * @endcode

 * will result in my_dest being TRUE since any array is greater than 3.

 *
 * @code
 * my_dest:
 *   plugin: evaluate_condition:foreach
 *   condition: greater_than(3)
 *   source: my_array
 * @endcode
 *
 * will result in my_dest being [TRUE, FALSE] since 4 is greater than 3 while
 * 2 is less than three.
