The simplest feature-detect for flexbox?

feature-detect flexbox.js

/*
 * Trying to feature-detect (very naive)
 * CSS Flexbox support. 
 * - Only most modern syntax
 * 
 * Is this nonsense?
 */

(function NaiveFlexBoxSupport(d){
  var f = "flex", e = d.createElement('b');
  e.style.display = f;
  return e.style.display == f;
})(document);

according to mcshaman post:

cssPropertySupported(['-webkit-box', '-ms-flex', 'flex'])

should be:
cssPropertySupported(['-ms-flexbox', '-webkit-box', 'flex'])

By the way:

return true

should be:
return name

so you know what syntax is used
