I would like to be able to:

I think I could use boost::tuple for this:

const BOOST_AUTO(sTupleVar, someThing); const BOOST_AUTO(sFirstResult, get<0>(sTupleVar)); const BOOST_AUTO(sSecond, get<1>(sTupleVar));

But how to declare a local variable inside a lambda function?

Hi Peter - I would recommend taking a look at the Phoenix library. It is more feature rich that Boost.Lambda. For local variables see here: http://www.boost.org/doc/libs/1_41_0/libs/spirit/phoenix/doc/html/phoenix/co... There are multiple methods for dealing with fusion sequences (tuples on steroids). You should find everything you need with Boost.Phoenix. It also has the upside of being more readable (imho). michael -- ---------------------------------- Michael Caisse Object Modeling Designs www.objectmodelingdesigns.com
