     Laplace{T, Dim, TM} <: TensorMapping{T, Dim, Dim}
 
 Implements the Laplace operator, approximating ∑d²/xᵢ² , i = 1,...,`Dim` as a
-`TensorMapping`. Additionally `Laplace` stores the stencil set (parsed from TOML) 
+`TensorMapping`. Additionally `Laplace` stores the `StencilSet`
 used to construct the `TensorMapping`.
