[boost] nested lambda question

Hi,

Is there a way to write lambda expressions in the form of:

   lamba_expression_x < lambda_expression_x

without repeating "lambda_expression_x"?  I tried this but it didn't work:

   (
     bind(_1, protect(_1))
     < bind(_1, protect(_2))
   )
   (lambda_expression_x)

I was trying to sort a vector of objects by a data member:

   std::sort(
      v.begin(),
      b.end(),
      (&ll::_1 ->* &s::i) < (&ll::_2 ->* &s::i)
   );

Thanks,
Brock
