But what if it's documented? For example, it's documented that setting the variable cursor-type not only sets a variable, but also has the side effect of changing how the cursor is displayed.
Disabling dynamic-cursor-mode could simply be another documented side effect of setting cursor-type. And DCM itself should also document that it's disabled when cursor-type is set, which is why I already included that in the docstring in the patch I posted.
Besides that, hooks on setting variables would be useful for debugging.
