I wanted to test this, so I tried the following:
using namespace boost::fusion;
    auto vec = make_vector(1, 3.14, "hello");
    auto push = push_back(vec, 42);
    auto pop = pop_back(push);
auto i1 = find<int>(pop);
    auto i2 = find<double>(pop);
assert(i1 != end(pop));
    assert(i2 != end(pop));
    assert(i1 != i2);
It doesn't compile for me. I think it should. And I would hope none of
the asserts fire. Will that be the case?
I think so. It's most probably a bug in the implementation. I'll go
check it out.
