Questions about improving code golf / code challenge skills

Examples

• How can I make shuffling this array shorter?
• How can I shorten these nested loops?
• How can I alias member functions in a short way?

Arguments

• For: These more basic questions might be attractive to new users (if they can identify and find them).
• Against: The questions are mostly language-specific from their intention and thus are not good fit or at least barely welcome here.
• Against: The better examples of this type of question and answer would naturally fit in the site as answers to the existing tips questions, without diluting the focus of the site.
