What happens when you assign space to a variable? I have this piece of code that goes; 
my $alphanumber = '';
for (1..$length)
    {
my $alphanumber .= $chars[int rand @chars];
}

Funny enough, when i append the result of $chars[int rand @chars]; to $alphanumber, the space disappears; What exactly is the meaning of assigning '' to a variable?
