[Grok-dev] Martian incompatibility between 0.11 and 0.12

[Martin Aspeli]

Hi,

The newly released martian 0.12 seems to not support the get_default 
keyword argument to martian.directive().

This breaks grokcore.annotation (and thus five.grok).

Is this an intentional change, or do we need some BBB code there?

Cheers,
Martin
