Evil! ;-)
An idea I haven’t taken the time to test yet would be to use
‘properties’:
(define python-foobar ;with Python 3
(package
(name "foobar")
;; Specify which Python 2 variant to use.
(properties `((python2-variant . ,(delay python2-foobar))))))
(define python2-foobar
(package (inherit python-foobar)
;; … stuff beyond the mechanical python 2→3 switch…
))
‘package-with-python2’ would honor this ‘python2-variant’ property.
Thoughts?
