Am I wrong?

Yes, you are wrong.

foo() is called with a single scalar argument which is precisely equal to scalar @ary or in other words the number of elements in @ary rather than a ref to it. I suggest you might like to 1) run the sample code where we print shift in foo and 2) follow the links I presented to learn more. I have a fair handle on scalar and array context BTW
