>> I've never seen that before. What does it do? It's exactly the same as a normal require. Ns allows vectors/seqs symbols/keywords to be used interchangeably. Some people use (:require) others use (require), ns just uses ns/namespace to get the data on the first of each item after the symbol. Yeah, there's a bug in the code, but let me try to redefine the problem. Assume I have a namespace called foo that defines a protocol (and hence an interface) called bar. I then also have a namespace called foo.bar. How do I tell the new syntax to import each? If I simply say "go get foo.bar" what are you going to load, the .clj file, or the java interface?
