This depends a lot on how important lookup speed is. The integer lookup
is bound to be faster than the string lookup. Though there's already
enough of a speed hit in the mysqlpp::Row stuff that it may not matter.

However, I can say that my code currently does use the numeric index 
lookup, because it knows what order the fields are in (they match
another list it's keeping). So there's at least one instance of real
world code that uses it.
