Be Careful with Go Struct Embedding

- Go's struct embedding allows composing types by embedding one struct within another.
- Example shows embedding `Position` and `Colour` in `Rectangle`, allowing direct access to embedded fields like `r.X`.
- Demonstrates a potential ambiguity when embedding structs with the same field name (`URL` in `FooService` and `BarConnectionOptions`).
- The code resolves the ambiguity by selecting the least nested field (`FooService.URL`), printing 'abc.com'.
- Highlights the importance of caution when using struct embedding to avoid unintended behavior.
