Thank you.

That is a good idea.

At the moment, io.m is north of 13k lines of code. I think we should
consider

- adding this get_environment predicate to a new library module, named
   probably env.m or environment.m,

- moving the existing io.get_environment_var predicate to the
  new module, leaving a forwarding predicate behind, and

- adding an "obsolete in favour of" pragma for that forwarding predicate.

Zoltan.
