Another data point: in our six-figure loc code base, we have 469 instances of getattr, 91 instances of setattr, and 0 instances of delattr. There is one instances of setattr(..., getattr(...)), and one instance of setattr(getattr(...), ...). > >+1 on .[] notation and the idea in general. > -1 on a syntax change for this. Somewhere between -0 and +0 for a builtin or library function like attrview().
