Here is a basic attribute definition from an O'Reilly Book:
sub new {
my $invocant = shift;
my $class = ref($invocant) || $invocant;
my $self = {
color => "bay",
legs => 4,
@_ ,
};
return bless $self,$class;
}
What I do not understand is why $self is not defined as a hash %self. Also,
if you were to only include @_, would you need a comma after it -- in other
words
my $self = {@_}; or {@_,};
