I love jython and use it frequently, and have over 3 decades of programming
experience----so not quite a newbie.

Jython works like magic for the most part but the integration is so slick
sometimes I forget which platform I'm on.  The Java objects start looking
like python objects and vice versa (which is the whole point, after all),
but it can be a bit confusing---even though it all just works.

So...I'm willing to cut the newbies some slack on their confusion here.
