Correctness is clearly the prime quality. If a system does not do what it is supposed to do, then everything else about it matters little.

Casting any pointer to void* could be considered a limited form of built-in, dynamic, parametric polymorphism.
By stretching things a bit further, you could even see const_cast and reinterpret_cast as falling into the same category.
a) inheritance and virtual functions
b) function overloading
are all built-in mechanisms for the *creation* of new polymorphic components in a C++ program. These casts simply *are* polymorphic components: you have no means of extending the set.
You could argue that you can use them (especially the void*) to create new polymorphic components, but then *I* wouldn't call it a built-in mechanism any more (it becomes a Turing-trivial argument).
Still, I appreciate the observation. I hadn't thought of the casts in this light before.

* use <pre lang="lang">...</pre> to insert a syntax highlighted code snippet.
For example, <pre lang="python">...</pre> will insert Python highlighted code.
* use <code>...</code> to highlight a variable or a single shell command.
* use <a href="url" nospam>title</a> to insert links.

I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my Amazon wish list, if you're curious about what I have planned reading next, and want to surprise me. :)
