We have. The `derivation` function supports producing multiple outputs,
and I'm sure that `mkDerivation` forwards this ability.

Well, at least now I know I didn't make any coarse mistake in the code.

To enable attributes to refer to each other, within the same attrset,
you need to put 'rec' in front of the attrset. In other words, instead
of oldAttrs: {, use oldAttrs: rec {.

Note that in order to build packages on the virtual Linux box, you need to

Nixops doesn't set that up for nix-build, which is why it fails to build.

Curry is indeed a beautiful language, and is essentially a
conservative extension of Haskell. I am surprised that more Haskell

Well, it does lack quite a few things right now, including on the

Chicken or Scheme are not at all what at all what I was suggesting as they
offer nothing in the way of purity or type-safety, which are the primary
motivation for suggesting Haskell.
