now i can do:

void foo() { protassign<bool> foorunning_assigner(foorunning, true); dojobs(); dofoooo(); }

and that's all. is there one such thing in boost already???

[Nat] In the forthcoming Boost serialization library:

http://www.rrsd.com/boost/

there's a state_saver template class that does what you're talking about:

This seems useful enough to promote to a library more general than the serialization library.

Yes. Anyone willing to make it into standalone library is definitely welcomed. /Pavel
