Research direction
Start with the documented partial-differential-equations section and reproduce the Julia 1.8 commands showing that ApproxFun.Δ exists while Δ is undefined. Trace the package's public export declarations for the Δ entry point; done means the documented unqualified Δ alias resolves to the Laplacian.
