Should languages related to programming and writing code be on-topic?
I would imagine questions employing pseudocode are okay, as this is a "Proposed Q&A site for those who study the creation and solving of puzzles." Therefore, it would only be natural to describe code you could write to, say, create or solve a Sudoku puzzle, in pseudocode. You could also use pseudocode to describe some sort of algorithm, or puzzle creation/solving technique.
However, would questions related to specific code that the asker needs help with be on-topic? For example, if a question requires an answerer to know the programming language used in the question, is it on-topic? How far should this rule go?
