Comment:

 The following is still a bug. It's a clear example of bad user input
 leading to an `AssertionError`:
 {{{
 sage: AffinePermutationGroup(['A',8,1])([0])
 ---------------------------------------------------------------------------
 AssertionError                            Traceback (most recent call
 last)
 ...
 AssertionError: Length of list must be k+1=9.
 }}}
