Hello,

Tests are supposed to be deterministic, so as such, it makes sense for
tests to be normal derivations, as is currently the case.

In that spirit, we should instead tweak <virtual-machine> so that we can
instruct it to build an autonomous VM with its own store.

OTOH, we could also have =E2=80=98container-eval=E2=80=99, similar to =E2=
=80=98remote-eval=E2=80=99,
which would be useful for effectful code, such as code that needs to
interact with the daemon.  Food for thought!

Thanks,
Ludo=E2=80=99.
