+ * Skip function for es5-shim module.
+ *
+ * Test for strict mode as a proxy for full ES5 function support (but not syntax)
+ * Per http://kangax.github.io/compat-table/es5/ this is a reasonable shortcut
+ * that still allows this to be as short as possible (there are no browsers we
+ * support that have strict mode, but lack other features).
+ *
+ * Do explicitly test for Function#bind because of PhantomJS (which implements
+ * strict mode, but lacks Function#bind).
+ *
+ * IE9 supports all features except strict mode, so loading es5-shim should be close to
+ * a no-op but does increase page payload).
