@halirutan Progress in lexical scope highlighting using stacks:
(still haven't addressed the f[x_] := part...)

Do you guys know of a simple automatic way to compute vertex normals for a polygon mesh? I want to get a smooth rendering, sort of like DiscretizeGraphics[Sphere[], PlotTheme -> "SmoothShading"], but I am hoping not to have to go to MeshRegion and specify PlotTheme -> "SmoothShading" then finally extract VertexNormals to do it. I have a list of coordinates and a list of polygons specified as indices.

@Szabolcs What's the mesh like? Triangles? Equispaced (think of the pre-version 6 ParametricPlot3D[])?
One very general method I'm aware of is the scheme in this paper.

@J.M. Made of triangles, like this (as displayed by BoundaryMeshRegion with SmoothShading):

@Szabolcs Yes, I believe Max's method will work in that case.
Something very funny about ArrayPad[]: try ArrayPad[{1, 2, 3}, {1, 1}, {4, 0}] and then ArrayPad[{1, 2, 3, 4}, {1, 1}, {5, 0}].

Wolfram Blog: Support Computational Thinking for the Entire Curriculum
posted on February 18, 2016 by Adriana O'Brien

Today is the second post in our Wolfram Programming Lab series and I’ll be highlighting how the Wolfram Language supports the development of computational thinking skills for almost any subject matter. Students solidify concepts and practices by making connections to all of their subjects, not just a few here and there. By incorporating computational thinking [...]

I would like to ask a question about poor performance of JoinAcross, but need to put some sample data up. Does StackExchange have a place for this? (Otherwise I could use Dropbox...)
