Oh, good point.  Well, OK then.

(In guile.scm we used a different convention: =E2=80=98guile-reader/guile-1=
.8=E2=80=99
vs. =E2=80=98guile-reader/guile-2.0=E2=80=99, where =E2=80=98/=E2=80=99 rea=
ds as =E2=80=98over=E2=80=99; the =E2=80=98name=E2=80=99
field follows a weird convention.)

BTW, I haven=E2=80=99t check whether this is the case already, but we need
something like

  (define (package-with-explicit-python p python)
    ;; Return a version of P built for PYTHON.
    (package (inherit p) ...))

so we can just write:

  (define python2-pytz
    (package-with-explicit-python python-pytz python-2))
