I thought I might could skip using $0 in structs by creating them as
singleton and reference that (instead of the localized $0-version) in
all instances of the abstraction. But then I noticed that I'm often
using the outlet of [struct] to detect clicks.

Assuming I have spread scalars of the same [struct] to different
canvases, is there a way to detect from the click message which canvas
the click originates from? In other words: Is there some way to
associate a pointer to a scalar with the containing canvas?
