Update to an update: Actually what I really wanted to do was: 

$condition{$key} = \@{$query->param($key)} || $condition{$key} = $quer
+y->param($key);

[download]
Why not use 
$condition{$key} = [$query->param($key)];

[download]
Which will give you an array-ref with 1 element when the parameter only has one value.

If you really need to, you can later do: 

if (@{$condition{$key}} == 1) {
   # one value
}
else {
   # ... zero or more than one value
}
