[Help-smalltalk] Traits

[Gwenael Casaccio]

Hi,

I've made an implementation of the traits: Traits are a simple composition 
mechanism for structuring object-oriented programs. A Trait is essentially a 
parameterized set of methods; it serves as a behavioral building block for 
classes and is the primitive unit of code reuse. With Traits, classes are 
still organized in a single inheritance hierarchy, but they can make use of 
Traits to specify the incremental difference in behavior with respect to their 
superclasses.

This is a young version: so the traits don't have state (In my first prototype 
they have it). That's pretty easy to add and the next step on my to do list.
