Well I guess it's a good thing no one ever had a double free in C :)

Can you elaborate on this? A destructor is a function that's built into an object. It's really not more complicated than that. If malloc/free are functions that should be used in pairs, then the constructor/destructor pair tries to provide a convenient and structured way to know where malloc/free go. You would call new in the constructor and delete in the destructor.

I'm curious to know what you prefer?
