works just fine, because (1+exp(t)).ldegree(t) returns zero. I think it should throw an exception just like (1+sqrt(t)).ldegree(t) does.

Agreed, ldegree should only work on things for which it makes sense. If you like to write a patch, I'll commit it. Besides that, our series expansion algorithms generally suck horribly. Maybe, I'll try writing something better sometime. Who knows.
