I thought about rescuing and re-raising the exception as a different
exception class, but maybe it is better to leave it as it is:

NameError: uninitialized constant Foo

This is the same exception you would get if you loaded a script file.

The way Marshal does it (in the case of a dumped class that is loaded
without having the class definition required) is:

ArgumentError: undefined class/module Foo

Maybe that's how YAML should do it for consistency?

I'd be happy with either way.
