"""

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.
