This is not a difference between lexical and dynamic scope. You can
make Maxima work this way by doing infinite evaluation, e.g.
ev(.., infeval).
The model obviously makes some sense because maple and mathematica use
it.
The model obviously is not the only one, and since Maxima's default is

A little experiment to see if ECL can be used as a library from
python, and after browsing through ECL's API, it looks like it should
be fairly straightforward to wrap the API with cython. The data format
that ECL uses for its objects should also be easy to interface with,
and since many of the at

Hi David,
concerning your original question:
In Debian sid (==unstable currently), there are Maxima version 5.17.1,

These versions are more recent than what currently comes with Sage.
