 Jan 18 answered How can I get Overlay to position graphics according to coordinates? Jan 18 comment How can I randomly generate a unique, unused symbol? Per session uniqueness is fine for me. That alone is way more than I'd usually need since I create, use, then throw away the symbols all within a Block or Module. Jan 18 comment Is there a way to have Plot draw points on a function where the function is undefined as circles as in textbooks? @raxacoricofallapatorius: In that case I would use Exclusions->x == 0.

Jan 18 comment How can I implement dynamic programming for a function with more than one argument? @LeonidShifrin: Just for the record, the way you did this is very cool and borderline black magic.

You just have to be careful to only evaluate CharlierC[n, a, x] for sybmolic a and x for my version, and always attach it to something beforehand.

I timed both versions, and yours is significantly slower on my machine. 0.016 seconds (mine) vs 1.185 seconds (yours) for n = 20. Still, very cool idea you have.
