A focused reference with a complete example. Numeric widths and experimental types still depend on the selected backend.

```yh
list of T
```


## Complete lists example

Use a list when order and duplicates matter.

Verification: type checked

```yh
list of text inventory = ["map", "torch"]
inventory.Add("key")
for item in inventory { Console.Log(item) }

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.language__lists"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/type--list-of-T-cce9ee/complete --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```
