Eclipse-PyUML ? Someone knows how good is it?

I just heard of a eclipse plugin that would do round trip UML for python.
Does someone know how good it really is?

I’m a bit reluctant to use a “TenTonHammer” like Java + Eclipse+ Plugin if it gets me nothing more than Scite+ !!!

UML is not good modeling python - or even true OO programming - that is not good at modeling program - its just modern flow cart some thing academics want to real world to be but it is not.
