Using “all” or “any” in this sort of situation may not be such a good idea.
More reasonable uses would be like
<https://developer.blender.org/diffusion/BAC/browse/master/io_export_paper_model.py>:
if any(uvface.flipped for uvface in island.faces):
if any(island.bounding_box.x > cage_size.x or island.bounding_box.y >
cage_size.y for island in self.islands):
