As a "matter arising" from my playing with the above, but of little real import
If my object is internally implemented using a single scalar value, and I use the IOO method of using the blessed ref representing the object as a key into a my'd hash, then I need 3 things. The hash (%hash), the scalar holding my data ($data), and a blessed ref ($self);
In the above, I am using \1 just to get a unique scalar ref which I can bless. I'm then using this as the key through which to access another scalar (the hash value) which is going to hold my actual data.
Now (my twisted type of) logic says, if I already have a scalar to hold my data, then I don't need to create another just to get my blessed ref, I could just bless a reference to the data. The problem is, you can't take a reference to a hash element until you have a key, and I want to use the reference as the key. Catch-22
Can I have my chicken lay an egg? Can I generate a self-addressing stringified reference?
The "mypackage=SCALAR()" bit is constant, so I would need to vary the hex value within the brackets until the address of the scalar allocated for the hash generated matched the hex value I generated. Is that possible? In my lifetime:)
