Florian, thanks for this hint !

We are highly aware of the advantages of Isabelle's rewriting machinery; 
for re-animating our code we have to rely on our own rewriter (which 
handles predicates like "(a + b * x) is_polynomial & 0 is_polynomial", 
while "is_polynomial" calls ML code) --- but then we shall learn to use 
Isabelle's "logical operating system";
