If I don’t describe a step, I get: NameError: undefined method call for class NilClass
NameError: undefined method call for class NilClass
because method(:call) in #arity is called on nil:
I think, would be better to raise a more descriptive error in this case.
@fenec what do you mean when you do “not describe a step”.
Is missing from the container or no method is defined in the class?
method is not defined in the class
