While I'm mildly uncomfortable with the precedent that would be set by including the contents of "sys" as built-ins, I must confess my objections are primarily aesthetic: I don't want to see the built-in namespace any more cluttered than is necessary -- or at least, any more than it already is. But "os" is another matter -- the "os" module contains things which might well not be present in an embedded Python environment (e.g., file and directory structure navigation, stat). Do you really want to force everyone to deal with that? Is it so much more work to add "import os" to those Python programs that require it? Of course, you might counter "why should we force everybody else to type `import os' just in case somebody wants to imbed Python?" But then, why don't we just include the whole standard library in __builtins__? Or, since that would be too much, maybe we survey the user community and include the top fifteen most included modules! Where do you draw the line? Do you really want to hard-code user opinions into the language? Right now, we have a nice, simple yet effective mechanism for controlling the contents of our namespaces. I don't think this would be a worthwhile change. -1. -M -- Michael J.
