I'm sorry to find a reason to contradict you, but I don't think that
Werner is proposing to put const "everywhere", just the places where the
contract of not modifying the contents of parameters passed as pointers
makes sense, such as in outline callbacks.
If you're worried that this will disrupt the current minor release API,
please note that Werner has already reverted the recent changes, and is
now seeking a nondisruptive solution leading to the next major release.
I can't believe I'm pleading the case of simple const declarations to a
man who describes himself as "a bit anal on API abstraction".
