@Dan,

You’re right, you’ll only get Categories working with static methods. Remember, it applies new methods to your class, but ‘helper’, ‘transformation’, or even light methods, not ‘core’ methods (imo, the ones that should care on your instance objects).

@Raphael

with modifier only uses the proper class methods, in the “with” post, all method used inside the { } are available in the class, and with categories, the method show are not in the Date class, but in the Category one… Got it?

In the past categories in groovy could only be static methods, which causes threading issues.
Do you know if anything’s changed? What are the implications of using categories in a muti-threaded environment?

That’s so similar to ‘with’ that got me confused for a little while.

Groovy is awesome. Thanks for the tip LT.
