Again, the goal is fast startup of command-line tools that only use a small subset of the overall framework; doing disk access for lazy imports goes against that goal.

Depends if you consider stat calls the overhead vs. the actual disk read/write to load the data. Anyway, this is going to lead down to a discussion/argument over design parameters which I'm not up to having since I'm not actively working on a lazy loader for the stdlib right now. For those of you not watching -ideas, or ignoring the "Python TIOBE -3%" discussion, this would seem to be relevant to any discussion of reworking the import mechanism: http://mail.scipy.org/pipermail/numpy-discussion/2012-January/059801.html <mike

So what is the implication here? That building a cache of module locations (cleared when a new module is installed) would be more effective than optimizing the search for modules on every invocation of Python? -------------- next part -------------- An HTML attachment was scrubbed...
