in thread Dereference an array reference

tye, excellent. Thanks. (You may recognize the example as one I cribbed and modified from you in one of the previous discussions on this topic.) This topic has become a bit of an obsession and I have indeed read a generous sampling of the previous postings.

So far, so good. So how do we put into words the difference in behavior in the two subs in the example? Update: merlyn provides the response to this question in his reply.

    "They return different values when called in a scalar context." ?

    You could make versions that return the first element or a reference to an array or that die when called in a scalar context. But they all return he same list in a list context.

    Trying to come up with some shorthand that describes both what they return in a list context and what they return in a scalar context without ever mentioning "context" is just a mistake in my book.
