* Cache the result of file evaluation (i.e, memoize evalFile()). This
prevents files from being evaluated and stored as values multiple times. For instance, evaluation of the ‘system’ attribute in NixOS causes ‘nixpkgs/pkgs/lib/lists.nix’ to be evaluated 2019 times. Caching gives a modest speedup and a decent memory footprint reduction (e.g., from 1.44s to 1.28s, and from 81 MiB to 59 MiB with GC_INITIAL_HEAP_SIZE=100000 on my system).
