comment A question about expanding complex functions of real arguments
You can get rid of the Re and Im by using the option TargetFunctions->{Conjugate}. But that still gives Sin and Cos for the exponential functions.

comment Recursive partitioning: Is there a better way to do this?
Looks great. The ArrayReshape documentation says introduced in 9.0, but unfortunately I'm stuck with 8.0, so I can't use that :-( But a +1, because I think this would actually be the perfect solution if only I could use it ...

comment Recursive partitioning: Is there a better way to do this?
I didn't know that you can put the condition inside a With. That's a nice way to get a restriction to valid lists. This alone is already a nice improvement to my version.

@Tangshutao: Anyway, I forgot: thank you for correcting my other mistakes (and I also forgot the @-attribution so you get notified).

comment Get a “step by step” evaluation in Mathematica
I just noticed that WalkD[Integrate[f[x],{x,g[x],h[x]}],x] results in an infinite loop of error outputs, each time adding an extra /. $Failed to the end.

comment How to replace While construct to NestWhile(functional-style) correctly?
I've now fixed the error in my code; my tests indicate it works now correctly. The error was rather stupid: I forgot to supply the initial argument and test function to NestWhile, and to close the remaining open function argument brackets.
