0.2.1

• Added two examples

• Moved traverseM operation to TraversableMonadOps
• Removed IO stuff
• Removed redundant type class instance aliases. Use IListMP instead of IListA, and so on
• Gave up on mixin inheritance chains, since dart2js still doesn't implement them properly

0.1.3

• Inspire dart2js to insert fewer cast checks and other runtime type paranoia, leading to significant performance improvements all over the place
• Type parameters for Option mapX operations
• traverseM operation for Traversable

0.1.2

• IHashMap, an immutable and persistent map that, unlike IMap, doesn't require a total ordering of keys, but instead relies on hashCode and equality of keys

0.1.0

• Dart Strong Mode compliance. This forced a couple of breaking changes:
  • Use Option<A> none<A>() instead of Option<dynamic> none
  • Prefer IList<A> nil<A>() to IList<dynamic> Nil
  • ...and so on for emptyVector, IMapMi, etc.
• Much improved type safety through type parameterization of commonly used methods/functions, using the prototype syntax. More type annotations to come!
