__DESCRIPTION__
$_ is the default variable, used when you are too lazy to
create one of your own and like clean looking code.
__EXAMPLE__
foreach (1..5) {
print "$_\n";
}
Is the same as:
foreach $_ (1..5) {
print "$_\n";
}
__FURTHER EXAMPLE__
Which incidentally is the same as these two:
print "$_\n" foreach (1..5);
print "$_\n" for (1..5);
