Hi,

My gcc 4.0 doesn't let me call apply_visitor on an rvalue variant. This is due 
to the Variant argument being a non-const reference, I guess. Is this a 
deliberate design decision (if so, the rationale should be documented), an 
oversight (in that case, it should be fixed), or a compiler bug (highly 
unlikely, since all of gcc 3.2 through 4.1 would then have it).

Testcase (== usecase) attached.

Thanks,
Marc
