Commonjs module bundler that hoists all modules into a single scope so they can be concatenated safely without wrapping them in individual function scopes.
This allows the resulting package to be minified more efficiently and minimizes the extra overhead at runtime from evaluating these modules. See: https://nolanlawson.com/2016/08/15/the-cost-of-small-modules/
We implement the ideas described in http://www.nonblocking.io/2011/12/experimental-support-for-common-js-and.html that have been implemented in Google's closure compiler.
- All local variables are prefixed with a module specific prefix so they don't collide with local variables in other modules when added to the same scope.
module.exportsandexports.*are replaced with a module specific global that other modules then reference directly.requirecalls are replace with the respective module specific globals.
