Mixity is good. All the attempt to artificially separate uses (zoning laws, Le Corbusier's Athen chart, cutting neighborhoods with highways etc...) are generally harmful to cities.
And I think imposing 2 simple rules would be enough to make any new neighboorhood significantly better:
1) You should be able to walk around each block in 10min or less (no giant blocks)
2) You should have at least 5 doors every 100m, leading to different uses (offices, shops, housing, nursery...)
