hmm.js

var fs = require('fs');

// then

hug(null, fs.writeFileSync, 'filename', 'data')

// should return the following function:

function() {
  fs.writeFileSync('filename', 'data');
}

// except we need to "preserve" context
// so if the first argument is null, then we're actually returning:

function() {
  var fn = fs.writeFileSync.bind(null);
  fn('filename', 'data');
}

// ideally we'd want a version that doesn't need the scope argument at all
// but I'm pretty sure that's impossible in javascript
