Previously, we'd just emit functions with `%s` in their function bodies. Also, the fFormatArgs wouldn't get cleaned up, so subsequent code would fill in the wrong format arguments in each place. There are still problems with function calls (`sample` is broken; function names are accessed before they've been declared or initialized) but this is a step in the right direction.
