6590,BOOST_AUTO fails on C++11 lambdas,Anders Kaseorg <andersk@…>,Peder Holt,"`BOOST_AUTO` fails on C++11 lambdas as follows (tested with g++ 4.6.2-14ubuntu2):
{{{
#!C++
#include <boost/typeof/typeof.hpp>
BOOST_AUTO(f, [](){});
}}}
{{{
$ g++ -c -std=c++0x test.cc
test.cc:2:1: error: lambda-expression in unevaluated context
test.cc:2:1: error: conversion from ‘<lambda()>’ to non-scalar type ‘<lambda()>’ requested
}}}

Although it’s apparently not possible to use `typeof` or `decltype` on a lambda expression, this could be fixed by defining `BOOST_AUTO` with C++11 `auto` on compilers that support it:
{{{
#!C++
#define BOOST_AUTO(Var, Expr) auto Var = Expr
BOOST_AUTO(f, [](){});
}}}
