Never mind, no need.

I'd argue that the problem is actually in phoenix::bind, it takes its 
arguments by const reference (as opposed to boost::bind by value and 
std::bind by &&+decay) and consequently fails cases like f.ex.

int * g( int * p )
{
    return p;
}

int main()
{
    int v[ 5 ] = { 0 };
    boost::phoenix::bind( g, v )();
}

but a regression is still a regression.
