–– Pkl Error ––
Cannot reference property `top` from here because it is not `const`.

x | @Ann { foo = top }
                 ^^^
at constAnnotation2#Foo.foo (file:///$snippetsDir/input/errors/const/constAnnotation2.pkl)

To fix, do either of:
1. Add modifier `const` to property `top`
2. Self-import this module, and reference this property from the import.

xxx | text = renderer.renderDocument(value)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
