This test isn't necessarily the best thing to check but if we do want to
keep it with some relaxed constraints then maybe we allow the norm to go higher
by a small amount iff the total loss is lower. So something along the lines of
```
norm2(l2.coef) < norm2(noreg.coef) OR
( (norm2(l2.coef)-norm2(noreg.coef))/norm2(noreg.coef) < 0.1 AND
l2.loss < noreg.loss),
```---
