self::implicit - provides '$self' in OO code, in an implicit way.

    package MathGuy;
    use self::implicit;

    # Write a normal constructor
    sub new {
        my ($class, $number) = @_;
        return bless({ number => $number }, $class);
    }

    # $self is now a special variable
    sub single() { $self->{number} }

    # It does not have to be said for method invacation
    sub double() { single * 2      }

    # '@args' too
    sub add {
        my ($n) = @args;
        return single + $n;
    }

    package main;
    my $tom = MathGuy->new(10);

    print $tom->double; #=> 20
    print $tom->add(3); #=> 13

This module adds $self and @args variables in your code like self.pm, and it also eliminate the need to say '$self->' in your code. Normal function invocation will become method invocation, if there is a $self variable in the caller context.
