+// when calling PETScWrappers::Vector::operator() (), the return type is a
+// reference object, not a reference to the actual element. this leads to the
+// funny situation that an assignment like v2(i)=v1(i) isn't really what it
+// looks like: it tries to copy the reference objects, not the values they
+// point to, as one would expect
+//
+// this was fixed 2004-04-05, and this test checks that it works

+// this is equivalent to the petsc_vector_assign_02 test, except that we use
+// operator+= instead of operator=. Now, this does not present a problem,
+// since the compiler does not automatically generate a version of this
+// operator, but simply performs the conversion to PetscScalar, i.e. the
+// argument to the user-defined operator+=. This is not exciting, but since I
+// wrote the test to make sure it works this way, let's keep it then...
