> Did you want a skilled programmer, or someone who memorized their Foobar Enterprise Framework cheat sheet? Because you're only interviewing for one of those.

People who ask common/simple insert language/framework here interview questions are sometimes looking to see if you at least minimum care enough to memorize the answers. Alternatively a sideways answer might work, like "I find that's no longer necessary since..." or "I'll be attending a 3-day dev conference that includes that topic..."

That said, it makes it look like they don't care enough about interviewees, when they put so little effort into the questions asked. To hire a skilled programmer, you need to present yourself as a skilled interviewer.
