if
you want to snag that one as well.

Ah, so we changed the behavior of the loader between 1.6.x and master.  I
think that explains the failures I was seeing; the spec tests in 1.6.x use
the `.loader` method while the examples in master use `.internal_loader`.
 If you pull examples out of 1.6.x please just keep this in mind for the
future.  It's probably best to pull examples from the same branch that
you're basing your work on.

In any event this is merged in now.  Thanks again for the contribution!
