This might be a big issue that we have to resolve before getting out of private/public beta: How programming-related can questions on Vim.SE be?
For example, questions about using Vim as a programming tool are probably on-topic. How about programming in Vimscript? What about questions that require a few lines of Vimscript, but are not purely focused on the programming aspect (ex. How can I do <task that requires 5-line script>)?
What other code-related questions are on- and off-topic?
