Yes ! Another user !

Because we're confident it works fine with 1D, but haven't tested things
thoroughly enough to be as confident with nD arrays. And we don't really
want to advertise something we can't deliver.

Actually, I prefer a code that bombs than one that deceives me into believing
it works when it does not.

All the moving functions of this module are wrappers to C functions. We use C
for performance more than for portability (cf the regular problems with
installation...). What you suggest sounds like a good idea, I'll kick the
ball to my co-author, he's the C speaker of the duo.

Thanks a lot for your support ! I wish I could spend more time on the code,
and less time on writing papers, however... Your suggestions and comments are
