After Christian mentioned how we could speed up interpreter start-up by removing some dead imports he found, I decided to write up a quick script that generates the AST for a source file and (very roughly) tries to find imports that are never used. People think it's worth tossing into Tools, even if it is kind of rough? Otherwise I might toss it into the sandbox or make a quick Google code project out of it.
Regardless, one interesting side-effect of the script is that beyond finding some extraneous imports in various places, it also found some holes in all. I have the script look for the definition of all and consider an import used if it is listed there.
