So I'm trying to create a joker.markup namespace for generating XML/HTML markup using Hiccup syntax. My new markup.joke includes a require of joker.html and that's failing:

16:17:09 ~/workspaces/golang/src/github.com/candid82/joker > ./run.sh --version && go install

Is there a way around this? My guess is that since std/html.joke is a built-in namespace there's an issue with having a dependency to it during generate stage?
