 In the following test case, the size of the vector is zero, while it
 should be three as that's what the vector is constructed with.

 {{{#!c++
 #include <boost/phoenix.hpp>
 #include <iostream>
 #include <vector>

 namespace phx = boost::phoenix;

 int main()
 {
         std::vector<int> v = phx::let(phx::local_names::_a =
 std::vector<int>(3))
         [
                 phx::local_names::_a
         ]
         ();
         std::cerr << v.size() << std::endl;
 }
 }}}

 If the local is used in a non-trivial way in the let block, the vector
 will be properly initialized.
