Comment (by wonder):

 Yes, thank you.  I was just converging on the same conclusions about
 `'limit` and using a python function to force re-evaluation.

 I've been assuming that when I see "limit( ..., x, 0.1 )" in a result,
 it's going to be passed back to maxima in a form that'll re-evaluate the
 limit.  I'd vote for implementing it that way rather than requiring the
 user to do "simplify_limit" manually at the appropriate times.  But I'm
 sure other users are doing infinite sums and such things that are better
 not to re-evaluate...
