lookup_by_name() is inefficient because it's built on field_num().

If efficiency is a concern, you shouldn't be looking up fields by name 
at all.  You should be using hard-coded indices into a Row array, or 
SSQLS instead.

I've sent this to the mailing list, because the discussion should have 
been kept there, and it's good info for the archives.
