Hi,

> Is this a bug?

No it's not, the following snippet should work better.

--8<---------------cut here---------------start------------->8---
(fold-packages
 (lambda (package lst)
   (if (string-prefix? "python" (package-name package))
       (cons (and=> (package-source package)
                    (lambda (source)
                      (origin-uri source)))
             lst)
     lst))
 '())
--8<---------------cut here---------------end--------------->8---

Mathieu
