OK, then I'll commit this patch when it will be ready.

OK, you know better :-)
However, I tried it and it doesn't work for me (note: I know nothing
about monads, gexps, etc.). When I try this:
(mbegin %store-monad
(set-grafting #f)
…)
the grafting doesn't happen, but when I try this:
(mlet %store-monad ((grafting? ((lift0 %graft? %store-monad))))
(set-grafting #f)
…)
grafting happens anyway. I have no idea what the problem is.
