   2  * Skip function for es5-shim module.
   3  *
   4  * Test for strict mode as a proxy for full ES5 function support (but not syntax)
   5  * Per http://kangax.github.io/compat-table/es5/ this is a reasonable short-cut
   6  * that still allows this to be as short as possible (there are no function "No"s
   7  * for non-"obsolete" real browsers where strict support is available).
   8  *
   9  * Note that this will cause IE9 users to get the shim (which should be close to
  10  * a no-op but will increase page payload).
