Re: semantic action problem

The good new is: the example is fine and works on gcc 6. The bad news 
is, it doesn't on msvc, so this seems to be the problem here. I tried a 
global declaration, i.e. this:

auto f = [](auto& ctx) { std::cout << x3::_attr(ctx) << std::endl; };
x3::rule<class test_rule> test_rule;
auto test_rule_def = '{' >> x3::int_[f] >> '}';
BOOST_SPIRIT_DEFINE(test_rule);

But that only changed the error type. So you could switch to mingw 6.2 
and would be able to use it, but maybe someone knows how to get it to 
work on msvc.
