Hi Guix,
sometimes Guix crashes. That’s sometimes because of existing bugs
(often in importers) or because I’ve just added something that doesn’t
quite work.
When Guix crashes it prints a backtrace and exits. Would it be possible
to change that behaviour and instead enter a debug REPL where I could
inspect values and resume after correcting the error?
That would be beautiful!

‘guix system’ has a ‘--on-error’ command-line option that we could
perhaps generalize somewhat. WDYT?
Now, two comments:
1. importers are “for developers”, so I’m personally more tolerant if
they’re rough on the edges ;-)
2. one can always do:
./pre-inst-env guile
scheme@…> ,use(guix scripts import)
scheme@…> (guix-import "foo" "bar")
;; crash!
scheme@…>[1] ,bt
