[aosd-discuss] Extension methods in C# 3

[sahilt(mail.utexas)]

Yes, they are "limited" form of method introductions. 

It arose from the need to add variability to an assembly (component).
The basic idea is that the group responsible for an assembly would
define variation points (heterogeneous crosscuts), and other groups will
extend them as appropriate for their task. 

This is closer to product-line work using FOP. However I mentioned they
are "limited" in their application because they are not true
refinements/extensions.

Cheers, 
Sahil
