Hello,
I made some improvements (?) of the Permutation function (in
improve_constructors_of_iet-vd.patch) in order to disable
{{{
sage: Permutation(['a','b','c'])
['a', 'b', 'c']
sage: Permutation([2,1,1])
[2, 1, 1]
}}}
We now have:
{{{
sage: Permutation(['a','b','c'])
TypeError Traceback (most recent call last)
...
TypeError: cannot convert l (=['a', 'b', 'c']) to a Permutation
sage: Permutation([2,1,1])
ValueError Traceback (most recent call last)
...
ValueError: the list l (=[2, 1, 1]) must contain each integer of
{1,...,n} one time
}}}
Is this a problem ?
Vincent
