Validation of arguments

It is implied that incoming array can be received from an unsafe place. It may not even be an array (that's why the $input argument is usually typified as mixed). The library try to process it without fatal errors.

But other arguments usually are not special validated. If the $path argument (see below) as array must have only strings or integers this is the area of responsibility of the external code. The library will not check each step.
