Consider changing the name of the "info" namespace to "self" or "this"

[sjperkins]

Similar to python, it reinforces the idea that the user is interacting with the current step

Other suggestions:

info.label -> self.name info.suffix -> self.name_suffix

Yeah, info was an ill-considered choice, it's been bothering me too. I do like the self suggestion.
