This looked interesting, especially after reading more about it in P.I.L., so I spent some time converting -nms to use this syntax.

It was a little more work than I bargained for, but in the end I really like how it forces you to be more strict about how data is being passed around between modules. The more I look into these modules it seems they're rather TeX-like in passing around large global variables everywhere.

Take a look:

Comments welcome. Would you be interested in trying this out in the master branch?
