Hello Stephen,

First, thank you for being interested by modules.
Module for Squeak need some motivated people.

Anyway, I admit I do not really understand what you have done. What is different from :

(Module @ #(People)) addAssoc: (Association key: #test value: 10) export: true.


And if you have Test defined into module #(People), you can perform this :
Test>>foo
  ^test

and what you have done ?

Regards,
Alexandre
