Not implemented[edit]
These are currently not implemented in Wren. Please implement some if you can. If any tasks are not possible or too complex in Wren, they should not be on this list.

Draft tasks without implementation[edit]
These tasks are drafts, meaning they largely need more work to turn them into full tasks. Perhaps you can help by trying to implement them in Wren (after all, one of the key requirements for a task being non-draft is multiple implementations, preferably in widely different languages) but be aware that this may be difficult because of lack of definition of the task itself.

Requiring Attention[edit]
Examples[edit]
These tasks have implementations in Wren, but somebody, somewhere, decided that the example implementation was faulty or in some other way requiring attention. If you're familiar with the task and language, please consider reviewing/correcting the example and removing the notice.

Other pages[edit]
These are other pages related to Wren which require attention; with your knowledge and assistance, we can improve the quality of the site's content.
No pages found.
Not Considered[edit]
These tasks are not generally counted toward "unimplemented", as somebody, somewhere, decided that Wren was inappropriate for these tasks, or implementations of them would be unenlightening. Feel free to try your hand at them anyway.

End of List[edit]
Again, feel free to try your hand at any of the tasks listed on this page.
