Eelco Dolstra	8c0590fa32	Never update values after setting the type ... Thunks are now overwritten by a helper function `Value::finishValue(newType, payload)` (where `payload` is the original anonymous union inside `Value`). This helps to ensure we never update a value elsewhere, since that would be incompatible with parallel evaluation (i.e. after a value has transitioned from being a thunk to being a non-thunk, it should be immutable). There were two places where this happened: `Value::mkString()` and `ExprAttrs::eval()`. This PR also adds a bunch of accessor functions for value contents, like `Value::integer()` to access the integer field in the union.	2024-03-25 19:21:25 +01:00

Rebecca Turner	df84dd4d8d	Restore ambiguous value printer for nix-instantiate ... The Nix team has requested that this output format remain unchanged. I've added a warning to the man page explaining that `nix-instantiate --eval` output will not parse correctly in many situations.	2024-01-11 16:34:36 -08:00
