``` ContractError: It looks like you are trying to use pattern-matching, but multiple definitions for function '' have the same contract for input parameters: None => String None => String...

## Example code: ``` Class A include Contracts::Core include Contracts::Builtin Contract Integer, Integer => String def self.hello return "Hello world!" end end puts A.hello ``` ## Actual behavior No errors...
