# Reports:Tasks not implemented in Elixir

**Awareness**

If

**Elixir**is a language you like, or are interested in, please inform your fellow members of the Elixir community; this page can't be emptied without your and their participation.

## Contents

## Not implemented[edit]

These are currently not implemented in Elixir. Please implement some if you can. If any tasks are not possible or too complex in Elixir, they should not be on this list. To mark a task as such, add **{{omit from|Elixir}}**, preserving the capitalization of the language, to that task. It will appear below under the "Not Considered" section.

## Requiring Attention[edit]

### Examples[edit]

These tasks have implementations in Elixir, 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.

### No pages found.

### Other pages[edit]

These are other pages related to Elixir 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 Elixir was inappropriate for these tasks, or implementations of them would be unenlightening. Feel free to try your hand at them anyway.

### No pages found.

## End of List[edit]

Again, feel free to try your hand at any of the tasks listed on this page.
