22:30 Bug #946: Function "ideal" evaluates the argument twice
- I have just run the test given in comment 2; now only the first one evals its arg twice.
Is this easy to fix?

- I think this has already been done. Changed status to "resolved".

-
- I have renamed @jacobian@ to @JacobianMat@; @jacobian@ is now in obsolescent (both for CoCoA-5 and CoCoALib).

-
- CoCoA-5 has a function called *@sylvester@*; should it not be called *@SylvesterMat@*?

Should it be *@TypeVectors@*?
