in thread Tying with a class method

I was under the impression that "use strict" would disallow me from using package level variables. I'm probably wrong though. Suppose if I wanted to make a hash a member of that class, regardless of whether strict minded or not, would it just work like: $self->hash{"foo"} = "bar"; and %self->hash ? Where I'd be able to do a statement such as 
tie %self->hash, "AnyDBM_File", "data", O_RDWR, 0644;

    The use of strict merely discourages the use of package variables. As long as a variable exists within the package's symbol table you're free to use it without it being fully qualifying.

    If you had a hash as a data member of the blessed object (which itself was a hash) then you would use it like so 

    # assign to hash
$self->{hash}->{foo} = 'bar';

# get keys from hash
keys %{$self->{hash}};

# tie hash
tie %{$self->{hash}}, "AnyDBM_File", "data", O_RDWR, 0644;

    If you're a little confused about how how classes and objects work I'd recommend reading Tom Christiansen's oo tutorial and perhaps also read up on references in perl.
