Yes, we know what reset does. You haven't given an argument as to why delete should do the same thing, and we've given you reasons why it isn't a good idea.
+1 If you want to say that a specific smart pointer has no interest in the pointee anymore, I think the expression p = 0; covers those semantics better. I don't know whether the current Boost.Smart_Ptr implementation supports that syntax, but it might be a nice addition. (I.e., p = 0; means the same as p.reset();.) delete p; really suggests that the pointee is going to be destroyed, so if that's not what you intend you shouldn't use the syntax. -Julian
