Comment:

 Thanks for the bug report, tyxla!

 I agree that this behaviour isn't ideal, and it's clearly inconsistent
 with the behaviour of the other `get_*` methods (except for `get_col()`,
 which calls `get_var()`).

 However, due to the age of this behaviour, and the potential to introduce
 subtle bugs into plugins that expect it, this isn't really a thing we can
 fix.

 If you run into any other behaviour you think should be fixed, please
 don't hesitate to open a new ticket - we're always happy to discuss these
 things, even if they're not something we can change. :-)
