The Code Golf FAQ says, "You should only ask practical, answerable questions". "Answerable" I get, but isn't code golf by its nature impractical, but fun. Aside from the impracticality of minimizing source code length, many of the puzzles that one can solve when golfing may have practical applications, but what about ones that do not? Are they off limits?
I wonder whether the "practical" blurb is Stack Exchange boilerplate text that accidentally got copied over.
