Subject: Ruby and AOP

I'm reading "The Pragmattic Programmer" right now and I'm at the part 
about orthogonality.  The authors mention AOP and give an example 
involving log writing wherein you can "weave in" some AOP ("Aspect 
Oriented Programming" for those not in the know) sexiness and log 
writing occurs (the converse behaves as you might expect)**.

It seems to me that this behavior is *sort* of like a mixin -- i.e. you 
can mix it in for a new behavior.  However, AOP code seems to be 
triggered when certain actions happen.

Does this sound roughly correct to those who have AOP experience?  Have 
any of you used AOP in your experience, and if so, where has it been 
most beneficial?

Thank you,

James H.
