Sorry, I was thinking about the problem correctly.  Try:

#!/usr/bin/perl
use Getopt::Long;
use Log::StdLog;

my %cmd_args = ();
my $cmd_args_ref = \%cmd_args;

GetOptions(
    "log-level=s"   =>  \$cmd_args{"log_level"},
);

sub log_format {
    my ($date, $pid, $level, @message) = @_;
    return "[$date][$level]: " . join(q{}, @message);
};

Log::Stdlog::import( {
    format => \&log_format,
    file => "$0.log",
    level => $cmd_args_ref->{"log_level"},
} );

print $cmd_args_ref->{"log_level"};

__END__

This re-runs the import function after the program has started.
