Delegate to method with arity > 0
Hello,
I was wondering what exactly the issue with delegating to a method with arity > 0.
And example of a use case
delegate :name, :name=, to: :user
This gem currently does not allow it
def ensure_delegate_method_is_valid
fail "#{delegator} does not respond to #{delegate}" unless delegator.respond_to?(delegate, true)
fail "#{delegator}'s' #{delegate} method expects parameters" unless [0, -1].include?(delegator.method(delegate).arity)
endHappy to add this feature if you think its worthwhile.
