Eelco Dolstra, can you explain this inhibiting of error detection?
I mean when writing this:
all-packages.nix :
vice = import ../misc/emulators/vice pkgs;
vice/default.nix :
{ dep1, dep2, ... }:
[..]
buildInputs = [ dep1 dep2 ];
you can't misspell dep1 dep2 without passing wrong arguments.
So I only see a reimplementation of the ellipsis here because they are
no not listed in all-packages neither using using callPackage nor using
ellipis.
So what makes the difference exactly?
It even adds a redundant function call to each package (thus some
complexity) to all-packages.nix.
