| This module is here for string completions. This means mostly stuff where |
| strings are returned, like `foo = dict(bar=3); foo["ba` would complete to |
| `"bar"]`. |
| |
| It however does the same for numbers. The difference between string completions |
| and other completions is mostly that this module doesn't return defined |
| names in a module, but pretty much an arbitrary string. |
