Comment:

 -1 to adding a default argument.

 We don't need this - the function already had clear defined behaviour and
 it didn't conform to it.

 The example code shared above relied on a bug in the code.

 You asked the function to return you an array of results and it didn't
 instead it returned you the result you would have got for a request of a
 single value if one had not been set.
