Add a dedicated operator=(std::initializer_list) that first resizes the QCLA, and then replaces the elements one by one. This should be usually faster than creating a temporary QCLA and then copying it, except for the case where the new array does not fit into the allocated stack - but this is IMO nothing to optimize for.
