Hi,
I think that Boost.ScopedExit needs at least to capture a variable. 
Boost.Local (which is currently reviewed) provides a similar feature 
that allows to pass void to mean no capture.

I guess this feature will be integrated in ScopedExit soon :), but in 
order to don't forget, maybe you could create a feature request on the 
Trac system.

Best,
Vicente
