Rats, that should be:
my $query = CGI->new({request => [%{$clusArrayHash[1]}]})->query_string;
Which means:
$clusArrayHash[1] is a hashref
%{$clusArrayHash[1]} is the hash
[%{$clusArrayHash[1]}] is a ref to an anonymous array containing
the hash "unrolled" to a list
The arg to CGI->new() is a hashref to a set of parameter key/value
pairs. When you use a listref as a parameter value, the query string
will be constructed to properly return the parameter as a list from
the param() call, so you can assign it back to a hash.
