When you dream code in that language.
Reminds me of an old joke, about the French teacher who told her students that they would "know" French when they dreamt in it. One student tried hard in class but was pretty bad at the language. But he came in one day all excited, saying, "Teacher, teacher, last night I finally had a dream in which everyone was talking French!" The teacher said, "Great! What was the dream about?" and the student said "Heck if I know, I couldn't understand a word they were saying!"
