Re: The current status of D?

int z = 0;
int foo(int x, int y) { return x + y; }
int bar(int x) { z++; return x * x + z; }
int baz(int x) { z--; return 2 * x + z; }
int main() {
     int w = foo(bar(5), baz(3));
     return w;
}

I think ',' in parameter lists are already sequence points.

They aren't, but a function call is a sequence point, so bar is guaranteed to 
be called before baz.
