I applaud you.

Fortunately, I am saved from my never posting promise because your one
liner, while lovely and impressive, only prints alpha's, not whatever you
want to put in the element set as mine does.  I am sure your example
illustrates some optimizations I could incorporate, which I will now think
about <sound of mind switching to 'ON'>.
