Correct. Relative imports are based on __name__ and don't work properly if 
__name__ does not properly reflect the module's position in the package 
hierarchy (usually because the module is the main module, so name is set to 
'__main__').

This is noted briefly in PEP 328 [1], with the current workarounds explained 
in more detail in PEP 338 [2].

Cheers,
Nick.
