Conceptually, one might have multiple different widgets wanting the 
editable span functionality which cannot easily share a base class, and 
also since I'm told Athena does very little client-side DOM work, to 
separate out the athena-specific code from the client-side DOM code.

But it would have worked just as well on the widget.

Third reason - VIMs syntax highlighting fails for encapsulated functions 
but works for bare ones :o)
