Ok, I stand corrected. This is something that PHP invented and is
non-standard. I'm guessing Ruby (or maybe just Rails) also uses this
convention, which is why it's the default implementation in
scriptaculous. If you do the variable that way in Perl, you have to
reference it with the brackets in your code as well:
$in{'item[]'} instead of $in{item} (assuming %in is your input hash).
Although there may be some frameworks that have modified it to work the
same as PHP, I don't really know.
