I have been trying to use Boost.bind to create an 'STL algorithm function object' to pass into another, 'higher order,' STL algorithm (e.g., to pass a for_each into a for_each). However, I am struggling to get bind to deduce the correct return type of the for_each function object.
The following might help:

Thanks a lot for the suggestion, I did take a look at Lambda library, and I saw that it used some extra type information in its STL algorithm wrappers (the 'sig') to help it figure out the return types. However, I am against using the Lambda library for other reasons, I only want to use the bind library. I'd appreciate some specific advice on how to get the type deduction with the Boost.bind library. Or is this just not possible with Boost.bind?
