I might have misunderstood.

For example,   `AccuracyScorer =  AsScorer(accuracy_score)` is either a [global variable](http://www.python.org/dev/peps/pep-0008/#global-variable-names), an [instance variable](http://www.python.org/dev/peps/pep-0008/#method-names-and-instance-variables) or both.

So the convention would be `names should be lowercase, with words separated by underscores as necessary to improve readability.`
