The code for serialization Expr nodes back into (pseudo-)Nix has been removed for being subtly error-prone and tedious to maintain. Instead, `nix-instantiate --parse` now prints a JSON representation of the AST. Usage patterns of the --parse flag I've found in the wild: 1. Check if a file is well-formed, i.e. discard output and test exit code 2. Get parser errors from a file, i.e. discard stdout and use stderr 3. Nixfmt uses --parse to test equivalence pre/post format, and that property is (should be?) preserved None of these should break with the current change Closes #487 Change-Id: Icdbaad17790f2ad8765fa08e02e6597ee4c7a909
