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:
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).
