// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
//     ie === undefined
// If you're in IE (>=5) then you can determine which version:
//     ie === 7; // IE7
// Thus, to detect IE:
//     if (ie) {}

//SUMMARY:
// a() @ b()  ==>  execute a(). if a() flags an async deferral inside it, 
// then wait to continue execution of the expression until that promise is 
// fulfilled, then continue execution *AT* b().
//
// more generally: X @ Y  ==>  evaluate X expression. if it was a function call
// call that deferred with a promise, wait until fulfilled then continue at
// Y. otherwise, assume that X had an implicit immediately fulfilled promise,
// and continue evaluating at Y.
