Re: Efficiency Question

In your example, $object already is a reference that's been blessed into a class. That's all an object is—a blessed reference. Passing in a reference to that reference doesn't gain you anything.

To be pedantic, you will take a hit from passing the object references since it will involve an extra ref/deref step. Of course, if that hit actually matters in any way/shape/form, either you or your code have some serious issues.	[reply]

OTOH, in addition to the insignificant performance hit, there may be a very significant maintenance hit. A future maintainer (maybe even the original author of the code!) may take a look at the superfluous ref/deref process, think "What the...?!?", and start looking through a ton of code for some clue as to why such a non-standard and round-about approach was used. The considerate thing to do is to avoid setting someone else (or, again, maybe even yourself) up for such a wild-goose chase.	[reply]
