comment Regarding Evaluated True
This appears to be a bug. At some point during the plot creation (inside System`ProtoPlotDump`iPlot) the Filling option value is processed to generate a full filling description for each plotted curve. This process does not take into account the Evaluated option and so sees only a single expression in your second example, and therefore only creates a Filling specification for one curve. I suggest you submit a bug report to Wolfram.

polygons[[9]] includes each perimeter point twice, so it is all hole.

comment Fit inside a module
As funnypony points out, you have simply missed a few semicolons at the end of lines. Voting to close as trivial mistake.

comment Upvalues and order of interpretation
@Kuba, I think this is more a question of evaluation control than pattern specificity. In QUAD["k1"]->2 OP needs QUAD["k1"] to partially evaluate to give an elementDefinition expression, but then for the elementDefinition SubValues not to evaluate - so that the UpValue definition kicks in instead when Rule evaluates. I'm not sure how this can be done. Personally I would steer clear of using built-ins like Rule as part of a homebrew syntax.

comment How do you apply an algorithm individually to an array with many graphs
Regarding your "obviously it doesn't like doing that" snippet: the outermost iterator should be given first. Like this: Table[stuff, {j, allgraphs}, {k, Max[VertexDegree[j]]}]

comment Maxwell propagator problem 2D
You probably want {ez, hy, hx} outside the Do loop so that it is returned from the module. Also I suggest you get the basic algorithm working before trying to compile it. And be aware of the difference between Dot and Times.

comment How to do algebra on summations of variable expressions?
@Mr.Wizard, I wonder if some of these Sum transformations are already built in, somewhere inside the colossal rule set for Simplify. But I agree wholeheartedly with your comment.

@Szabolcs, in general rule order does matter though. Or is it different for Dispatch?

comment How to programmatically extract mathematical formulas from Word with Mathematica 9?
It looks like the WordprocessingDocument is this from the Open XML SDK. I had a quick look at it too, but I'm not at all familiar with .NET and it seemed too much like hard work for a Sunday distraction :-)

comment How can I Integrate large trigonometric expressions more efficiently?
No, please don't delete your original. I think it's good to keep it as it shows how you would approach similar problems in cases where the integrals aren't trivial.

comment How can I Integrate large trigonometric expressions more efficiently?
+1 Same approach I took, though since n is an integer I didn't bother with Integrate at all. Just Expand[2 Pi expr]/.{(Cos|Sin)[_]^2 -> 1/2, (Cos|Sin)[_] -> 0}
