A function that both directly depends on global mutable state (and
modifies it) can hardly be called pure. Can you (anybody) give a
D "pure" definition that allows for the program that I've posted
and still makes "pure" useful?
Functions that are pure may only mutate mutable state explicitly passed
to them, or created within.
struct S;
int f(S* p) pure;
S* n();
int g = 0;
int main() {
S* s = n();
f(s);
return g;
}
Is main() guaranteed to return '0'?

No. What is the point?
