[Israel.pm] defined @array

[Yossi.Itzkovich at ecitele.com]

Hi,

I have a function that returns a list. The list could be empty.  When I
have an error I want to return undef.

In the calling code I want to know if the list is empty or I got undef, so
first I check:
if (defined @array)....

But -w gives me :
"defined(@array) is deprecated at... May be you should just omit the
defined ?"

But then I will not be able to differ between empty list and undef, isn't
it ?
