*
* This function is written with the goal to be *extremely* error tolerant, as such
* it should meet the following requirements:
*
* - It must not rely on the analyzer (in fact, the analyzer must not be used here),
* because at the time global classes are parsed, the dependencies may not be present
* yet, hence the function will fail (which is unintended).
* - It must not fail even if the parsing fails, because even if the file is broken,
* it should attempt its best to retrieve the inheritance metadata.
*
* Before changing this function, please ask the current maintainer of EditorFileSystem.
