* This function can be thought of as a hybrid between PHP's array_merge and array_merge_recursive. The difference
* to the two is that if an array key contains another array then the function behaves recursive (unlike array_merge)
* but does not do if for keys containing strings (unlike array_merge_recursive).
* See the unit test for more information.

* Note: This function will work with an unlimited amount of arguments and typecasts non-array parameters into arrays.
* Since this method emulates `array_merge`, it will re-order numeric keys. When combined with out of
* order numeric keys containing arrays, results can be lossy.
