nix/tests/functional/lang/eval-fail-genericClosure-operator-not-function.err.exp
Robert Hensing ca787bc3e0 tests: add error tests for builtins.genericClosure
Covers error conditions for:
- Invalid argument types (not an attrset)
- Missing required attributes (startSet, operator)
- Type mismatches (startSet/operator not correct type)
- Element validation (elements not attrsets, missing key attribute)
- Key comparison errors (incompatible types, uncomparable types)
- Operator return value validation (not a list)
