The article Are destructors overloadable? talks about overloading the destructor.
This raised a question: Can a destructor have parameters?
I've never used or seen a destructor with parameters. I could not come up with an example of a reason to use parameters to the destructor.

A special declarator syntax using an optional function-specifier (7.1. 2) followed by ˜ followed by the destructor's class name followed by an empty parameter list is used to declare the destructor in a class definition. So no, destructors do not take parameters.
Destructor rules 3) Unlike constructors that can have parameters, destructors do not allow any parameter.
Properties of Destructor:The destructor does not have arguments. It has no return type not even void. An object of a class with a Destructor cannot become a member of the union. A destructor should be declared in the public section of the class.
There are specific rules that make an overloaded delete function a destructor function: the function must have just one input argument, which is an object of the class, and it must not have any output arguments.
Section §12.4 of C++0x draft n3290 has this to say about destructors:
Destructors
A special declarator syntax using an optional function-specifier (7.1.2) followed by ˜ followed by the destructor’s class name followed by an empty parameter list is used to declare the destructor in a class definition.
(emphasis added)
So no, destructors do not take parameters. (The 2003 standard has the exact wording of the above paragraph.)
