Re: how to get stl algorithms to accept functions?

I'm trying to use remove_if with boost::xpressive::regex_match but I
can't figure out how to convince remove_if to accept regex_match. I've
tried casting this and that, but I did not really get anywhere. Is
there a good discussion on this somewhere? In the code below I have
two options one with bind2nd and the other with lambda _1. Can anyone
enlighten me on how to get either or both to work? Thanks ...

    "abc",
    "uvwxy1.ef",
    "123abc.ef",
    "234." };
  list<string> strgs( data, data + 8 );
  xpr::sregex rex = xpr::sregex::compile( "abc[0-9]+\\.efg" );
  bool match = xpr::regex_match( string( "abc56.efg" ), rex );
  cout << "match = " << match << endl; // works
// strgs.remove_if( bind2nd( xpr::regex_match, re ) ); // opt 1
  strgs.remove_if( xpr::regex_match( _1, rex ) ); // opt 2
  return 0;
