Hello Greg, I'm hesitant to incorporate any 'magic' like this into the core library. It's a matter of aesthetics, but I'm no big fan of this kind of do-what-I-mean API style. I prefer explicitness. If you want to work on a library that does a lot of helpful things under the covers, I think that's best tackled as a layer on top of Postmodern, so that people who want a different approach, or just the basics, don't have to deal with it.
