I am trying to figure out the best way to test for the number of elements in an array. Basically, if the array only has one element, I want to do A, and if it has anything else (meaning 0 or > 1) I want it to do B. I am currently doing "if (@foo == 1) ...", but not sure if that really works... I have code below for the different ways I know to do this... Please give me any suggestions. Maybe there is a better way? 
# foo only has one element...
if (@foo == 1) {
   ...
}

my $num_elements=@foo;
if ($num_elements == 1) {
   ...
}

if ($foo[0] ne "" && $foo[1] eq "") {
   ...
}
