Yea, and note, I'm still open to the idea of better names than "interp". I'm still not entirely happy with that name. I'm even half-tempted to use "_".
The only one problem I've found with doing it in library though: Far as I could tell, it seems to require the caller uses string mixins, which makes actually using it a little uglier and more verbose than I would like. Maybe I'm overlooking something obvious, but I haven't been able to find a way to change it to either a template mixin or even just a plain template without sacrificing to whole point of interpolated strings: specifying the arguments 100% inline.
What I think would be ideal is a language enhancement to allow "interp" to do its job without the extra syntactical noise. That would not only give us good interpolates strings, but would likely have other applications as well.
