I use the code below for calling stored procedures with a varying number of arguments.

How can this be written in a more compact way? Ideally I would like the 3 lines of code between the ----------- lines to be written on a single line only: 

 
use strict;
use warnings;

our $n ||= 10;

# -----------
my @qm = ();
push @qm, '?' while $n--;
my $str = q{CALL DB_PROC_FOO(} . join(q{,}, @qm) . q{)};
# -----------

print $str;

__END__
$ perl -swl qm.pl -n=1
CALL DB_PROC_FOO(?)
$ perl -swl qm.pl -n=2
CALL DB_PROC_FOO(?,?)
$ perl -swl qm.pl -n=3
CALL DB_PROC_FOO(?,?,?)

No matter how great and destructive your problems may seem now, remember, you've probably only seen the tip of them. [1]
