pointer_cast and safe_reinterpret_cast.

char* p = pointer_cast(new int()); // OK
long p = pointer_cast(new int()); // Error
int** p = pointer_cast(new int()); // Error

char p = safe_reinterpret_cast(new int()); // Checks size
long p = safe_reinterpret_cast(new int()); // Checks size

Great post!

I can think of a use for this code. With some basic type specialization we can assign a unique ID for each type in our program.

This code is presented as an original example (perhaps too original?) for this kind of technique/approach. The very same technique can be applied in many real-life situations, and this simple example only strives to demonstrate the basic concept – in order to get people familiar with this kind of thinking.
