Hi,
I am trying to figure out what the best way to enable move semantics in
Boost.Optional. I tried to pick at how Boost.Variant does it. If I
understand correctly, move operations are only defined if compiler supports
rvalue references. I wonder why it doesn't use Boost.Move, which would
enable move semantics even for compilers w/o rvalue references. Is there
any reason for this (that I should also take into account for
Boost.Optional)?

Regards,
&rzej
