Although I also take a reference for many situations (update: including this one :)) , your original example actually needs only braces around where an identifier name would go to work (update: at least functionally if not optimally) :
for ( 0..$#{$self->session->param('item')} ) {
    print $self->session->param('item')->[$_]."\n";
}

Other examples (of syntax) for using such braces for this:
# to iterate the elements directly
for my $conf ( @{$self->session->param('item')} ) {
    print "$conf\n";
}

update: this one is also not optimal for the example because of its subroutine call being repeated a few times, (as shmem has meanwhile pointed out) but there are some more common situations where the for (;;) does optimise by avoiding a generated iteration array ... I often work with large A of Hs without subroutine calls and use this approach... 
for ( my $i; $i <= $#{$self ->session->param('item') }; $i++ ) { 
    print $self -> session -> param('item') -> [$i ] . "\n";
}
