Added back a bunch of static's to gen/classes.cpp, it's not superfluous, it makes the functions internal to the compilation unit, and we don't call them anywhere else.

module mini.foreach6;

struct S
{
    long l;
    float f;
}

void main()
{
    S[4] arr = void;
    foreach(i,v;arr) {
        v = S(i, i*2.5);
    }
}
