Seems like this would be more useful.
Perhaps. Do you care to explain why?
It works generically on lvalues and rvalues, so that if someone hands you a function object f, and some_algo is more efficient when it can modify its first argument in-place, you can do some_algo( mutate_rvalue(f(),0), x ); HTH, -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
