v0.9 - 2015-04-24

• MAJOR fix in pattern-matching: If the return contract for a pattern-matched function fails, it should NOT try the next pattern-match function. Pattern-matching is only for params, not return values.

• raise an error if multiple defns have the same contract for pattern matching.

• New syntax for functions with no input params (the old style still works) Old way:

  Contract nil => 1
  def one

  New way:

  Contract 1
  def one
  

• Prettier HashOf contract can now be written like this: HashOf[Num => String]

• Add SetOf contract

• various small fixes

v0.8 - 2015-04-03

• code refactored (very slight loss of performance, big increase in readability)
• fail when defining a contract on a module without include Contracts::Modules
• fixed several bugs in argument parsing, functions with complex params get contracts applied correctly now.
• added rubocop to ci.
• if a contract is set on a protected method, it should not become public.
• fixed pattern matching when the multiple definitions of functions have different arities.
• couple of new built-in contracts: Nat, Eq.
• changed Invariant to invariant: invariant(:day) { 1 <= day && day <= 31 }
• prettier error messages (Contracts::Num is now just Num, for example)
• support for yard-contracts
