Actually, no.

Let's just leave it at this: I've seen the eye-glazing properties of  
various policy-based approaches firsthand, and had more than my fair  
share of debugging and maintaining policy-based implementations. Yes,  
policies are interesting; yes, they are useful in some designs. And  
yes; you should be very careful when choosing to use them.
