I'm not sure it's *that* much easier... all you're saving is one parameter.

Hm.  I'm not sure how wxPython handles that, and if it would be possible to 
impose such a system on top of it.

Wax follows the wxPython standard here.  Since most Wax controls derive 
directly from wxPython classes, it would make little sense to add lowercase 
methods to the mix (next to the existing uppercase methods), or to convert them.

I personally like 'from wax import *', kind of like how Tkinter is usually 
imported.  Either way currently works, though.  Should I use the "lazy" 
importing (which is admittedly useful), then the star-import would not be 
possible anymore, I think.
