with(Student[LinearAlgebra]);
example1 := Matrix([[1, 2, 3], [4, 5, 6], [6, 7, 8]]);
whattype(example1);

testproc := proc (A) print(whattype(A)) end proc;

testproc(example1);

The whattype() calls output:

Matrix
proc() ... end proc

I don't understand why what is a Matrix type outside the procedure seems to change into this unrelated type? This is really bizarre. I feel like it may be something outside my code? Thank you.
