eval/eval.go:441

• [nitpick] Consider providing a clearer and more descriptive error message for the DOT case in delete, or implement the expected behavior instead of using a TODO message.

return s.NewError("TODO remove map dot:" + index.Inspect())

token/type_string.go:88

• [nitpick] Verify that the updated _Type_name constant and index mapping correctly reflect the intended token order, ensuring the DEL token is appropriately positioned relative to others.

• [nitpick] Review the transition code in SmallMap Set: confirm that using m.smallKV[i:m.len-1] correctly captures all elements after the insertion index when converting to a BigMap.

res := &BigMap{kv: make([]keyValuePair, 0, m.len)}
