I recall that some parts of PDL have been factored out in the
past. Would it be better to merge into PDL the kind of changes
proposed for PDLA instead of replacing in the future PDL by PDLA? PDLA
could become some kind of development branch of PDL. I would be glad
to experiment with it. I do think it is a good idea to break-up PDL
into smaller parts that are easier to install and that can be installed
as they are needed. Currently, the automatic installation of PDL (say
running 'cpanm PDL') can succeed though leaving many parts uninstalled
due to missing dependencies. My students have suffered believing they
had succeded and then trying to use some parts of PDL that were not
operational. For similar reasons, I guess, the binary distributions of
PDL (at least in debian, apt install pdl) only install a subset of the
functionality. I guess this might be alleviated with finer-grained
packages that force installation of their dependencies.

Ok.

As I answered in the other list, in our group we do use regularly.
