Thank you, thank you, THANK YOU! The old vimscript was so weird I had
to do hours of trial and error just to do simple things, and there were
a lot of things I couldn't do at all. Much/most of this was for
VimOutliner, and I didn't want to require VimOutliner users to need to
install Python extensions, so I used VimScript.

Can I use some of one and some of the other, so I can slowly switch
things to the new one?
