Subject: [Boost-users] [boost.tuple] Nested tuples and tie

Dear list,
is there a way to make constructs like this one work?
double a, b, c;
tie( tie( a, b ), c ) = make_tuple( make_tuple( 1., 2. ), 3. );
This leads to the first parameter of the "outer" tie getting initialised by the
return value of the "inner" tie. That means a temporary gets passed by
reference, and the compiler (sort of reasonably) doesnt want to do this.
Best regards,
Julius
