CHANGES

0.4 (2014-01-14)

• arginfo has been totally rewritten and is now part of the public API of reg.

0.3 (2014-01-06)

• Experimental Python 3.3 support thanks to the future module.

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.
