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?
Could you all please grant me this wish - let's not get into that vortex
again? It renders everyone involved unproductive for days on end.
Thanks. -- Andrei
