On a related note, if you're using new and delete you can simply delete a pointer-to-const without jumping through any const_cast hoops, though I often wish I had a way of blocking that for APIs where the callee doesn't take ownership of a const Foo*.

Is that actually a standard though? ISTR some compilers complaining if you use delete with a const pointer (sorry, this is from ages ago, I cannot recall which compiler...)

You can make a fair argument that using delete with a const pointer is a type error, after all the data can hardly be considered const if it has just been eradicated...
