Nice try, and thanks for correcting my missing bind invocation, but still
no tomato!

struct S { int i; };
bool pred_fn( int i, int j ) { return i >= j; }
void f( std::list<S> & l, int i )
{
using boost::phoenix::arg_names::_1;
using boost::phoenix::arg_names::_2;
boost::function pred_obj = _1 >= _2;
// OK
l.remove_if( bind( & S::i, _1 ) >= i );
// OK
l.remove_if( bind( pred_fn, bind( & S::i, _1 ), i ) );
// Not OK.
l.remove_if( bind( pred_obj, bind( & S::i, _1 ), i ) );
}
Results in this error...

Thoughts?
Thx, Rob.
