This comment represents the my biggest frustration with current programming tools & practices. You shouldn't have to include any libraries. Ever! And you shouldn't have to rewrite some code that does something that's already available and well-written. That, and, if you want to include some functionality, there will be 13,000 versions of the same functionality for you to review before you decide which one to learn and commit to. (And it is easier to write it yourself sometimes.)
There's no reliable way for languages themselves to standardize and aggregate the work that others do. You just hope the language designers are willing to put up a new version, (and that it's a decent one) and they end up doing it ever-so-slowly because it's not automated in any way. Hand-pick and re-roll. There's no metric-based signaling or automated analysis or anything, it's just whatever your experts opine.
For basically every piece of software I work on this would have horrible security implications. Let me spell it out in black and white: every time someone does a deployment, by default it will download code from the internet and incorporate it into production code. All one would need do is subvert one external code provider and they'd have the ability to inject code into countless production systems at will. How much do you trust github or bitbucket? Would you give them the keys to your business, and your customer accounts?
