| CUE allows duplicated field definitions as long as they don't conflict. | |
| For values of basic types this means they must be equal. | |
| For structs, fields are merged and duplicated fields are handled recursively. | |
| For lists, all elements must match accordingly | |
| <!-- ([we discuss open-ended lists later](lists.md).) --> | |
