BUGFIX: Recursive function lookup typo

v2.3.1

Update changelog

Improve first-class function API

Allows you to capture functions in a shared map that we can use for lookup:

$functions: (
  'darken': get-function('darken'),
  'lighten': get-function('lighten'),
);

That way, you shouldn't have to make any changes to your existing color maps when upgrading Sass.
