Another C feature you didn't know about: the standard allows
to create a mutable pointer to const data and mutate it.
I didn't? Of course I did. In C++ other threads can write to
const objects. The function receiving a const objects is not
supposed to write to const. Const cast is supposed to be used
for calling legacy const interfaces without a const signature.
Of course you didn't. In C you can mutate const object without
cast. But it's not an issue because it's not what is usually done
and usually const works as expected.
