There some discussion going on the ruby-core mailing list about which standard libraries to _remove_ from the official ruby source, now that RubyGems is going in. I thought I'd let all you plebians know. I personally can't believe that YAML and Webrick are being proposed for the chopping block. Anyway, that's not the main reason I've written, I'd actually like to suggest the Ryan Davis' ParseTree make it _into_ the standard library. Why? Well, It's a low-level inspection library, written in C, that does something quite useful --let one inspect code, in a very general manner (s-expressions). Short of a better way to achieve this kind of inspection, I think this library definitely deserves to be readily available. T. P.S. Ryan, I'd like to veto your opinion on this manner (with exceptional to ParseTree's technical merits, of course). Don't take that the wrong way, it's just that, 1) you've already principally stated you want to unbundle as much as possible from Ruby and 2) this is your library. So so either way, it seems you have a pre-defined bias. ;-)
