249 Adding attributes to a container like this is discouraged, because the |
|
250 container modification is visible even in repositories that do not |
|
251 have the extension loaded. Therefore, care must be taken that the |
|
252 function doesn't make assumptions that the extension was loaded for the |
|
253 current repository. For `ui` and `repo` instances, a better option is |
|
254 to subclass the instance in `uipopulate` and `reposetup` respectively. |
