bug: that is not defined in #teach, since the scope is that of the outer object

[ghost]

Brainz::Brainz.new.teach { |iteration, error| return self.inspect }

This returns the self of the outer object, hence that is not defined.

nvm, think the training didn't get called due to a bug in another part of my app (nothing to do with your gem).

Just the error message might want to be more descriptive someday.

Thanks for this gem btw.
