### Nested paths
The value of `GIT_CLONE_PATH` is expanded once and nesting variables
within it is not supported.
For example, you define both the variables below in your
`.gitlab-ci.yml` file:
```yml
variables:
GOPATH: $CI_BUILDS_DIR/go
GIT_CLONE_PATH: $GOPATH/src/namespace/project
```
The value of `GIT_CLONE_PATH` is expanded once into
`$CI_BUILDS_DIR/go/src/namespace/project`, and results in failure
because `$CI_BUILDS_DIR` is not expanded.
## Special YAML features
It's possible to use special YAML features like anchors (`&`), aliases (`*`)
