Re: [Boost-users] [boost][lambda] How to adapt container objects?

I need to create an index using a std:vector as the sort key. boost::lamda and std::sort seem just the thing:

<snip>

I don't understand the error message, and can't make out from the documentation why this doesn't work. Do I need to extend the return type deduction system somehow? But operator[] is not one of the action types.

It's other_action. It ought to be documented at http://www.boost.org/doc/html/lambda/extending.html. Will fix shortly. In Christ, Steven Watanabe
