show p; expands to monitor operations for p.x and p.y, but reference marking ignores Stmt::Show/Stmt::Hide, so the struct and fields are still reported unused.
Expected
show/hide statements should count as uses of the variable/list they target. For struct values, expanded monitor statements should mark the struct and generated fields as used.
