`let` and `subject` declarations are not intended to be called
in a `before(:all)` hook, as they exist to define state that
is reset between each example, while `before(:all)` exists to
define state that is shared across examples in an example group.
WARNING: subject accessed in a `before(:all)` hook at:
This is deprecated behavior that will not be supported in RSpec 3.
There's a ton of places where 'subject' is used in 'before' stanzas... :(
I expect this was fixed when #522 was merged :)
@hatt thanks! closing.
