Title: Hash does not respond to delete!

There's a nasty re-monkeypatch in `spec_helper.rb` which is masking a bug in the real code:

```ruby
class Hash
def except(*keys)
cpy = self.dup
keys.each { |key| cpy.delete(key) }
cpy
end
end
```

After removing this, the test suite explodes:

```

```

Digging deeper Hash does not respond to delete!, so implement this in a right way.
