Why do you need this?

These are theoretically accessible with op() but you will have to extract
the expansion variable and point manually. I will add get_var() and get_point()
methods. Then you can get the coefficients by iterating over coeff() from
ldegree() to degree() (and ignoring zero coefficients).

These are accessible with op(). You don't need (and don't want) to access
seq/overall_coeff directly.

Here's another idea for finding all properties of all objects of a GiNaC
expression: if you archive the expression, all relevant information will be
stored inside an archive object. Currently, it's all safely hidden inside,
but I see no problem in making the data available for public read access. It
should then be easy to, e.g., convert an archived expression to a Python
initializer.

Bye,
Christian
