Well, the problem was that when I was inside a scheme session, and
tried to read the environment variable I assigned, there was nothing
defined - probably because it is defined only within the subtree of
the nf-chunk. So, when I know how to define values that continue
outside that subtree, maybe I won't need to call new-env....

I think it must be possible, because counters behave in this way -
their value is valid from a certain point in the document onwards.
