Defined in:
lib/command-set/arguments.rb

Overview

Using FiddlyArguments is sometimes unavoidable, but it kind of stinks. You assign blocks that validate, complete and parse the input. You’re probably better off subclassing Argument.

n.b. that FiddlyArguments can’t use the subject keyword to use the application state as their basis
