Hello, How can I parameterize the type of the following data class so that any type can be a Candidate? type Candidate = String data Poll = Poll [Candidate] [Ballot] My initial thought was to simply put a type variable in place of Candidate, but that clearly won't work: data Poll = Poll [a] [Ballot]

...

Not in scope: type variable `a' For context: I am building a voting library that addresses the issue of polarized American politics by implementing the Virtual Round Robin electoral method with a Maximum Majority Voting algorithm for breaking cycles. The beginnings of the library are available at http://github.com/canadaduane/votelib/blob/master/vote.hs What is a good approach to the parameterized type issue? Thank you, Duane Johnson
