Hello, this works fine, struct A {   template< typename X >   void f( bool ) {     bind(&A::f<X>, this, _1)( true );   } }; whereas template< typename Z > struct A {   template< typename X >   void f( bool ) {     bind(&A<Z>::f<X>, this, _1)( true );   } }; gives me trouble in the at the line of bind form of "expected primary-expression before ‘>’ token". I've tried numerous typedefs, but that didn't do the trick. Many thanks in advance for help on this, Rutger
