Indeed. It doesn't work for `OptoRuntime::Math_Vector_Vector_Type()`, but `alloc_type(const Type* t)` you mentioned can be specialized: it is only called as`AllocateNode::alloc_type(Type::TOP)` and `AllocateArrayNode::alloc_type(TypeInt::INT)`.

FTR I'm perfectly fine with leaving it for a future cleanup.
