comment Get DownValues that do not involve patterns?
one way of extracting the inputs/outputs: Cases[DownValues[f], (_[Verbatim[f][value : Except[_Pattern]]] :> result_) :> (value -> result)] (general note: i figure this out by using FullForm. e.g. FullForm[x_] => Pattern[x, Blank[]])

comment How to generate a random snowflake
i just noticed this isn't particularly in line with what OP was looking for. i don't think it'll hurt anyone though and it's in the Christmas spirit

comment Module that finds the sum of digits of any given positive integer
@rola please see my answer to this question. it's important to understand that Mathematica's syntax is very "raw", in that there are no keywords. Module is not a keyword. it's a regular symbol/function that you could make your own version of. the important syntax is :=, which expects a pattern on the left and basically anything you want on the right. the purpose of Module is to create local variables. if you don't need local variables then you don't need Module, you can just write the expression, or e.g. f[x] := (Print[x]; x)

comment Module that finds the sum of digits of any given positive integer
@rola Look in the Mathematica documentation (F1 button in Mathematica), it is very useful. Total is basically the same as Plus @@ # & which is the same as Apply[Plus, #] &. The main difference, I suppose, is that Total allows you to specify the level (for example you can add up all the elements of a matrix, instead of its rows).
