Comment (by viboes):

 The statement

 {{{
 index[0] = 1;
 }}}

 concerns two operations, the operator[] which returns a reference and the
 assignment operator.

 In order to make this work we will need to use expression templates

 operator[] would return a proxy reference, let call it at_type, that must
 store a reference to the synchronized_value instance and the index.

 We would need to overload the assignment operator on at_type so that it
 can do what you want as an atomic operation.

 I have not too much time to implement this kind of cosmetic features, but
 a patch would be welcome. Do you think that you can do it?
