[Boost-users] lambda parse tree access

Hello, i am writing a multiple dispatch framework and as i am feeling scientific i am gonna try to add a predicate dispatch fearure to it. For that i need to build big nested expression template instances that represent the predicates, so that i cant evaluate them at the time of method invocation. As an additional feature i want to sort the predicates for specifity (one predicate is true at a subset of cases of another predicate and is as such more specific) and for that i need access to the parse tree of a lambda expression. Is there documentation available on this topic and does lambda have a public interface for that? Does it make sense to use lambda as a library for writing expression template algorithms? Thanks in advance
