Sorry for being stubborn, but I' like to decode multivalued parameters
*without* identifying them by name.
That's precisely why reading multiple values into an array is not
applicable.
Is it possible that, when I do "my %in = $q->Vars" (should be "%in", not
"$in", shouldn't it?), %in contains not the actual names and values, but
only references, and that that's why any subsequent attempts at deleting
key/value-paris are unsuccessful?
