    From http://stackoverflow.com/a/15196301/:

p.s. i'll be glad to hear you solution to my other question stackoverflow.com/questions/15274927/…. ( maybe you have a better solution). Royi Namir 2013-03-08 07:03:32Z

The answers do include good examples of both eagerly-loaded/instant (e.g., jantimon, SLaks) and lazy-loaded singletons (e.g., Kolink).
Though, for a few variations on lazy-loaded: :)
It is possible to return the instance (single-instance-constructor.js) each time, but this will probably be confusing unless [it's not actually new](http://jsfiddle.net/cois
