So which one is it?

That doesn't answer my question.
A few years ago, I recall, you were arguing that for functions
which are or may be exported to a DLL, thus all Phobos functions,
it is impossible to predict how the functions will be used. Thus,
you argued, the functions' input has to be validated, even if
invalid parameters can only be passed to the function as a result
of a program bug, and never user input.
So, to repeat my question: which one is it? Have you changed your
mind, or are there exceptions to the rules in the post you quoted?
