You would name it whatever you want. You would then access multiple valuse by assigning to an array when requesting the values:

my @selected = $query->param("my_multiple_select");

Or just use it in a list context:

foreach my $sel ( @{$query->param("select")} ){
    ...
}

You might also want to name it myname[] just to remind yourself that multiple values are allowed.

Have a look at CGI::State. If you follow a naming convention it sets out it will take a CGI.pm query object and turn it into a multidimensional data structure.

The name is off and it wouldn't be the best thing for maintainability but I can see how it could be handy.
