- This doesn't work still, but now for new reasons.
```
NoMethodError:
undefined method `b' for #<Binding:0x0000000107a7e088>
binding.b
^^
# ./test/migrator_spec.rb:72:in `block (3 levels) in <top (required)>'
```
and if I add `require "debug"` to the spec_helper again it gives:
```
LoadError:
cannot load such file -- debug
```
but, doing a `require "debug"; binding.b` in `migrator_spec` _does_ work.
Where is the require coming from where it works some of the time but not through all of the layers we have?
