The Big Question(tm):
How can we avoid redundant work?
My (somewhat utopious) suggestion:
maybe we should think in components that use/modify

I like the sound of that. There shouldn't be any code
that we share. Because we all have different styles,

I think the bulk of redundant work is on standard
effects or modules. We don't want to define anything
