Since I'm using the sjs:bundle module a lot, I tend to come across modules that are missing @requires. I'll post them in this thread as I come across them.
For starters, the "mho:surface" module is missing an @require for "sjs:sys". Personally, I think it would be great if the hostenv check could be done at compile-time rather than run-time, but that doesn't jive well with JS or SJS.
