is (ind=ind) returns true
is (equal(ind,ind)) returns false.
limit(1/x,x,0) returns infinity but the document says it returns und.
limit(sin(x),x,infinity) returns und
limit(sin(x),x,inf) returns ind
in 5.18.1
I suppose I should try 5.19 :)

(ps. Mathematica says limit(sin(x),x,inf) is [-1,1], which was discussed
earlier.]
