If you meant

? Pol([[1,2,3],[4,5,6]~])
%1 = [1,2,3]*x+[4,5,6]~

? Pol([matid(2),[1,2;3,4]])^2
%5 = [1,0;0,1]*x^2+[2,4;6,8]*x+[7,10;15,22]

I do not think this is a bug. If anything, this is be useful for creating
FlxX.

This is not really a bug but it can still create not very readable objects:

? f
%2 = (x,y)->x*y + 1
? type(f)
%3 = "t_POL"

where f was created by

? f=Pol([(x,y)->x,1],'y)

Anyway, I do not really mind, it's just that I was surprised when I applied

Pol to a non-standard vector.

Long life to FlxX !
