Detailed Description

Dedicated worker for evaluating attrset.

Motivation: eval things in attrset (e.g. nixpkgs). (packages, functions ...)

Observation:

1. Fast: eval (import <nixpkgs> { }).
2. Slow: eval a whole NixOS config until some node is being touched.

This worker is designed to answer "packages"/"functions" in nixpkgs, but not limited to it.

For time-saving: Once a value is evaluated. It basically assume it will not change. That is, any workspace editing will not invalidate the value.
