xformat feedback

Hi Sean, thanks for http://hackage.haskell.org/package/xformat, found via http://www.serpentine.com/blog/2009/09/25/riddle-me-this . It sounded like the easy way to get that problem solved. Here's what I was thinking as I tried to use it: "Would it kill you to include *one* example in the package or haddock docs ?!" Sorry, but you did ask for comments to improve it. :) I found out more at http://github.com/spl/xformat/tree/master/tests/ . What I was hoping for was a way to do printf, without the variable arguments which make reuse troublesome, but still using standard printf format strings. Does this lib do that ? Best - Simon
