What is the proper way to test if an array is empty ?
Probably the easiest is:

if (@array) {
        # not empty
}
else {
        # empty
}
# or...

unless (@array) {
        # empty
}
This works because an array in scalar context returns the number of 
elements it contains.  If it contains 0, that will equate to false.  
Anything else will be true.
