Comment (by jrf):

 Widening the accepted data type for the function, while the function is
 only intended to deal with strings, is 100% the wrong solution. If we go
 down that road, every single function in WP would need to be able to deal
 with every single type of input.

 It should be fixed at the source of the problem. Fixing the symptom is not
 the way to go.

 Think of it this way: would you treat a brain tumor (actual problem) with
 a paracetamol to combat the headache (symptom) ?
