I've tried to distinguish levels of proficiency with a language in my CV. For example, "expert/highly proficient", "proficient", or "familiar". There's only one or two that I'd consider myself "highly proficient" in, and probably a half dozen that fall into the latter categories. Gives you some flexibility to say "hey, I've worked with [language X], but I'm not as strong as I am with [language Y]"
