This is already used in the `wibox.layout.manual` layout. It makes
the widget easier to use. Previously, using the imperative syntax
was necessary for most grids.
The goal is to catch cases where the return value exists, but is
forgotten. There was a large enough number of them to turn this
into a real check. Initially, I just wanted to implement it to fix
the problems, then delete the code. But since this is so common, I
think it is worth the annoyance.
Now always call both check_widget and make_widget_from_value. This
should make it a lot less confusing when randomly trying to create
a widget as all ways to do it slowly converge toward an unified
one.
ldoc has a magical `@classmod` module type which tries to detect
what is a method and what is a static function. It fails about as
often as it works. This commit makes everything explicit to remove
such issues.
