Hi Maxim,

No, the the version is not wrong. pypy tracks CPython’s development
(features, standard library) and thus implements a certain “Python
version”, in this case 3.6, even though pypy’s own version says
something else. But, as you said, pypy in Guix is not really useful
anyway right now without any packages.

(That was the idea of the symlinks by the way, providing pypy as a
drop-in replacement for python-wrapper in python-build-system.)

Cheers,
Lars
