Answering this in the general case.

If you know that the object is stored as a hash, yes you can access it like 
a hash - but that's your risk. When you upgrade your modules and it switches 
to being stored some other way - you get to fix all your code. That's one of 
the things that many perl coders like - to the degree that it's perl 
culture - you *can* poke inside the box if you want but you have to accept 
the risks that go with that.

As far as other optimisations, yes it's nice to develop some good habits but 
you don't want that to be at the expense of maintainability. Even if you're 
a team of one - you will still have to come back and maintain your own code 
at some future time. I have plenty of code that I wrote and understood very 
well at the time, but is a confusing mess now! So if an optimisation doesn't 
impact maintenance too much it's worth turning into a habit. eg print with a 
list rather than using concatination
