I'd like to ask a question on U&L where we could create several implementations of transpose using the various languages (awk, perl, bash, etc.) but this type of question seems as though it would be off topic, yet I and others have answered at least a 1/2 dozen or so of these questions just this week. So it seems like a canonical Q&A to this topic would be valuable.
What's the best way to proceed?
BTW: I can provide references to Q&A's if need be.
