| # Duplicate Fields | |
| 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).) | |

| s: { | |
| y: 2 | |
| } | |
| l: [ 1, 2 ] | |
| l: [ 1, 2 ] | |
