There is no inherent advantage in that.  In fact, it is slightly less 
efficient than the original code because the `a' and `b' identifiers need to 
be resolved first, and it requires more maintenance effort because one needs 
to need track the identifiers.

 window.setTimeout(function() { x.a(); }, 10);

The asynchronous call is unnecessary here, though.
