Thus, there is no indication in the variant that anything has gone

An exception being thrown (well, propagated) is a fairly strong indication that something unusual has happened. Variant does not swallow the exception that caused the rollback.

Thanks, my bad; however, my excuse is there was no indication in the passages which I cited that exceptions are propagated. OTOH, prompted by your reply, I looked at: http://www.boost.org/doc/libs/1_52_0/doc/html/boost/variant.html#id1244408-b... which does indicate that operator= propagates exceptions: may fail with any exceptions arising from the assignment of the content of rhs into the content *this. Sorry for noise :( -regards, Larry
