* Named functions can be used as default exports from a bundle
* Method calls are assumed to mutate the owner (i.e. `foo.bar()` mutates `foo`) ([#13](https://github.com/rollup/rollup/issues/13))
* `options.indent` can be used to control indentation of resulting bundle. `options.true` (default) means 'auto', `options.false` means empty string. Alternatively specify whitespace e.g. `' '` or `'\t'` ([#5](https://github.com/rollup/rollup/issues/5))
## 0.7.0
* Ensure statements are always separated by a newline ([#9](https://github.com/rollup/rollup/pull/9))
