Oh nice, that's really neat! I didn't know about <parameterized>, that
achieves exactly what I was hoping for.

Is there a reason you use 'with-parameters' in 'graft-derivation/shallow'
and not in 'input-graft' and 'input-cross-graft'? I attached a patch
below where I do that and also set %current-system and
%current-target-system (although I'm not sure they are strictly
necessary because of the 'parameterize' in 'bag-grafts').
Then, the changes to the gexp-compiler of <parameterized> are not
required to allow for strings in the 'replacement' field in
tests/grafts.scm and the tests still pass.

Cheers,
