Currently, using the hhtps://yhetil.org/guix public-inbox instance,
coupled to the Emacs package ’piem’, I already have that. :-)

Basically, I use Emacs code from emacs-debbugs to query, then the Emacs
package ’piem’ [1] coupled [2] to the Python tool ’b4’ [3] and done.

Well, maybe using Scheme code for query Debbugs via Mumi, then instead
of,

>   (invoke "git" "am" "-s" patch))

’invoke’ the B4 tool.  Other said, start to move all the hard work of
extracting the patches and application to an external tool and just glue
with Scheme (instead of Emacs lisp as ’piem’, for instance).

Then this Python B4 could be reimplemented (or adapted) using Scheme.
