What method would you expect it to use, to overwrite B's contents of type A?

A's own operators are the only way the compiler has to do so. Even a default operator is still an actual function that gets called.

A gslice_array is a reference to the actual elements of an array specified by a gslice. The way to get a gslice_array is to call operator[](gslice) on a valarray. The returned gslice_array then permits carrying operations out on the referenced subset of elements in the original valarray. For example, operator+=(valarray) will add values to the subset of elements in the underlying valarray this gslice_array refers to. Parameters: Tp Element type.
