in reply to Adding scalars but with a twist..

This can easily be done using eval(), even under strict: 
use strict;
my $a1 = 3;
my $a2 = 4;
my $a3 = 5;

my $sum = 0;

for ( 1..3 )
{
    eval "\$sum += \$a$_";
}

print $sum;

p.s.
i personally would prefer to rewrite the script you have to update (as stated in previous post), because not doing so is false lazyness in my eyes.
