When trying to compile the following:

std::vector<int> v; v | boost::adaptors::transformed([] (int x) { return x; });

I get a bunch of compile errors. If I replace the lambda with a function defined normally, it works.

You must use #define BOOST_RESULT_OF_USE_DECLTYPE

C++11 lambda can't apply non decltype-base result_of.

Thanks a lot; worked like a charm. Of course, in the interim I figured out that the function will be rather more complicated than I thought so I'm happier with it defined normally, but that'll be good to file away for future reference. :-) Evan
