NPM is a worse idea than Joe's as Joe was talking about a single community vetted monorepo. Not a free for all of individual repos.

With Joe's idea everything is up front and part of the language and not a bulletin board of packages near the checkout line at the git supermarket. This way simple stuff like isint() can make its way into the languages official standard library. This should eliminate the uncertainty of 3rd party packages maintained by a random number of individuals that can be taken down or tainted at any time.
