Yep, it definetly should be [z, log(z)]. And even [z, log(z), q] in my case.
It's close, but not quite what I wanted.
I think I'll just substitute a number into D. Then sympy handles it
smoothly.

You can also try rcollect (though see
https://code.google.com/p/sympy/issues/detail?id=3862; I think that
function could be improved).

I think it needs to be collect([z, log(z)]). See the documentation. The
third argument does something different.

Thank You for a quick reply.
.collect(z) does not quite succeed, since I also have logs.
.collect(z, log(z)) didn't do what I expected.
Nevertheless I think I'll be happy with collect, subs and coeff
