My point was that a raise-style exception shouldn't be wrapped in a
(%exception ...) and then again in an &exception-with-kind-and-args,
this wrapping should ‘collapse’. Seems like a bug in Guile.

Anyway, your patch to Guix looks reasonable to me, though it would be a
good idea to look into fixing the double-wrapping in Guile.
