Glad dhh is starting some pushback.<p>Just as a minor aside, for anyone interviewing out there, don't fret about syntax that much. If you forget, tell your interviewer "i forgot the exact syntax, but let's assume it takes in x,y,z".<p>The key thing I'm look for is an understanding of what a function does and how you're going leverage that to solve the larger problem at hand. I'd hope other interviewers are the same way.
