Explain why classes are better that partial functions.

[proofit404]

def action(a, b):
    def do(c, d):
        return ...
    return doc

versus

class Action:
    a = ...
    b = ...
    def do(self, c, d):
        ...

• inner function repr vs attrs repr
• ugly return in the bottom of the line
• do = partial(action, a, b) mixes configuration and execution arguments in function signature
