D takes the type of the last element. I guess it has been decided to take the
common type but hasn't been implemented. Anyway your two reasonable options are:
auto ts = to!(T0[])([...]);
auto ts = [new T1(), to!(T0)(new T2())]
I recommend using std.conv.to instead of a cast because it is safer. Though
cast is a no-op and isn't any less safe in this case.
