By ibolmo:

Took a look at the `has.js` source and doesn't seem to have a loader to load all the definitions at the start. Say if you wanted to skip all the testing.

By the way, seems as if has supports require.js so perhaps we'd need Core.js to try: `typeof has == 'undefined' && !(has = require('has'))`
