assign::list_of works poorly with class constructors

[tailsu@…]

try compiling the following snippet:

#include <boost/assign/list_of.hpp> using namespace boost::assign;

class foo { public:

foo(const vector<int>& a) {}

};

void bar() {

foo a(list_of(0));

}

at the line 'foo a(list_of(0))' the compiler (VC8) thinks I want to call the copy contructor of foo, instead of the constructor that would cause a conversion to vector<int>. This case requires an explicit conversion, or using a different constructor prototype that doesn't overload the copy constructor.

Please, advise which is the best way to use list_of in this scenario.

Does

foo a((vector<int>)list_of(0));

not work?
