in reply to Problem with string as HASH ref while strict refs in use

you have something like

package Cats; sub new { bless {}, shift } # generic constructor ;) sub purring { $self = shift; $self->{key} = "foos" };

what's happening is that you are calling that method on the package, instead of on an instance of a class...

my $self = Cats->new; $self->pruring; # will set the key, since $_[0] is $self Cats->purring; # will treat the invocant ("Cats") as a hashref, since + $_[0] is the package name

perlboot has more. (and yes, It is deliberate that i didn't write it in terms of your code ;)
