[svn r231] Changed: warnings are no longer treated as an error. Added some comments and cleaned up CallExp::toElem a tiny bit. Fixed: struct literals always reported inplace assignment even if they allocated a temporary. Fixed: passing stuff to a D-style vararg which did inplace assignment was generated suboptimal code.

module moduleinfo2;
import std.stdio;
void main()
{
    ModuleInfo[] mi = ModuleInfo.modules();
    writefln("listing ",mi.length," modules");
    foreach(m; mi)
    {
        writefln("  ",m.name);
    }
    assert(mi.length > 50);
}
