If you're not a Perl programmer, you'll probably have some difficulties.

No, => is a "fat comma". It's pretty much equivalent to , but with an
added feature that if it is preceded by a bareword (like LOCATION), the
bareword is automatically quoted.

The arrow operator is used between a reference and a subscript. So
$self->{PRESENT} means that $self is a hash reference, and you want to
access the value of the key 'PRESENT' in the hash referred to by $self.
Please read 'perldoc perlop'. Even better, read a Perl tutorial.
