Question:how to use Jordan form inside a proc?

I know this has to do with name scoping issue. But I do not see how to fix it now.

Calling J,Q:=LinearAlgebra:-JordanForm(A,output=['J','Q']); works in global, but not inside a proc.

What is the correct way to use this inside a proc?

>	restart; A:=Matrix([[1,2],[3,4]]); J,Q:=LinearAlgebra:-JordanForm(A,output=['J','Q']);

Matrix(2, 2, {(1, 1) = 1, (1, 2) = 2, (2, 1) = 3, (2, 2) = 4})

Matrix(%id = 18446745500542083790), Matrix(%id = 18446745500542076678)

>	restart; foo:=proc(A::Matrix) local J,Q; J,Q:=LinearAlgebra:-JordanForm(A,output=['J','Q']); end proc; A:=Matrix([[1,2],[3,4]]); foo(A);

Matrix(%id = 18446745500542658910)
