+description: __path__ attribute of a package has a different type (single string instead of list of strings) in MicroPython
+cause: MicroPython does't support namespace packages split across filesystem. Beyond that, MicroPython's import system is highly optimized for minimal memory usage.
+workaround: Details of import handling is inherently implementation dependent. Don't rely on such details in portable applications.
