That's why namespace prefixes can be composed, i.e.
(##namespace ("eckerdal#utils#" append!)) (##namespace ("feeley#utils#" sort!))
It is just the usual hierarchical nesting idea.
I think I will need to think up a better way of explaining the approach I am taking here. I'm avoiding having any global prefix at all, because prefixing like this is either prone to clashes (like C) or gives very long names (like Java)
