Now try the trap. Remove builtins.deepSeq result.state from the key line, use s.key + 1 directly, and run it again. genericClosure will churn through all 100,000 steps without complaint. Then Nix tries to evaluate .total, forces a chain 100,000 thunks deep, and dies. The error appears to come from the field access, not the computation. That misdirection is exactly why sternenseemann shelved the whole approach.
