This has been confusing me this week as I keep thinking "worldll" is polygons:

silicate::TRI(quadmesh::worldll)
 Error in .local(x, ...) : invalid layer names 

There's really no problem to do it, but it would be pretty heavy -perhaps error with a pointer to TRI0 which is cheaper, or better simply to anglr::as.mesh3d (or QUAD). It's the same there though, should DEL return a result? The QUAD-lazy thing has been working so it might be time to propagate that through for the structured cases (and cc. https://github.com/hypertidy/anglr/issues/111 QUAD special case for polygons)
