Instead of piping to less, I pipe to cut,

    guix refresh -l python-numpy | cut -f1 -d':'

And rebuild, I use:

    guix build $(guix refresh -l python-pytorch | cut -f2 -d':')

or if I need a readable list:

    guix refresh -l python-scipy | cut -f2 -d':' | sed 's/ /\n/g'

I agree that the output of “guix refresh -l” is cumbersome. :-)
