CHANGES

0.2 (2013-12-19)

  • If a generic function implementation defines a lookup argument that argument will be the lookup used to call it.

  • Added reg.mapply(). This allows you to call things with more keyword arguments than it accepts, ignoring those extra keyword args.

  • A function that returns None is not assumed to fail, so no fallback to the original generic function is triggered anymore.

  • An optional precalc facility is made available on Matcher to avoid some recalculation.

  • Implement a specific PredicateMatcher that matches a value on predicate.

0.1 (2013-10-28)

  • Initial public release.
