Why not have the syntax closer to BOOST_FOREACH?

I.e.

  FOREACH_ROW(batch, 0, row) {
  
  }

You could also consider using the c++11 for loop syntax, but that might be more 
trouble that it's worth.

FWIW the google C++ style guide says "Try not to use macros that expand to 
unbalanced C++ constructs, or at least document that behavior well."
