Any objections to extending itemgetter() and attrgetter() to be able to extract multiple fields at a time?
# SELECT name, rank, serialnum FROM soldierdata map(attrgetter('name', 'rank', 'serialnum'), soldierdata)
# SELECT * FROM soldierdata ORDER BY unit, rank, proficiency sorted(soldierdata, key=attrgetter('unit', 'rank', 'proficiency'))
Breaking the symmetry with getattr() bothers me a little, as does the signature change that occurs when multiple arguments are given (returning a tuple, whereas the single argument returns just the retrieved attribute).
For itemgetter, I'd like to see multiple arguments eventually map to multi-dimensional slices (to preserve symmetry with indexing syntax).
Call it -1 for itemgetter and -0 for attrgetter.
Cheers, Nick.
