I was just listening to an NPR radio broadcast that was discussing Ulysses and James Joyce. They were interviewing residents of Dublin and one woman said that Joyce wrote about the life of a flâneur (I'm paraphrasing since the interview was long.)

What surprised me was her use of the French word flâneur - one who walks about without hurry, with no specific destination.

Is this common? This is the first time I've ever heard an English person use the word.
